 Hey, what's up, folks? We'll go back to another layer by layer in today's tutorial. We're going to make a 3d printed in place handle Let's jump right into it so this is a new project that I'm working on it is a MIDI fighter project using the new Raspberry Pi Pico and what I wanted to do for this enclosure is to have a handle so I can Grab this handle and have better Mobility with it right what's cool about the handle is that it's 3d printed in one piece So it can't be disassembled and it has articulation so it can go full 180 degrees It works really well for this project and I think it would be probably useful for other projects as well Not just in closures, but maybe you want to make a pull drawer or something. So here's the mechanism Printed in one piece. So you have these hinges here two of them and they are free spinning So these spin like that and you can't quite really see how it's assembled Like what's on the inside here because you can't take this apart So this can spin freely here and then you have these two mounting holes So you can secure this to a surface Like a case or like I said a drawer But yeah, this is what we're gonna design today in Fusion 360. So let's just jump right into the fusion Here we go All right, so here is the model in Fusion 360 and what's cool about is that it's interactive So I have some joints some joints set up so that I can interact with the model and Test out the angles of the freedom of degrees right so you can see here probably can't do that But it'll stop about right here and right there and that's pretty much all I wanted to do So that is How you can interact with it in this model here. So This is actually how it prints In this orientation So if we look on the underside these surfaces that I'm selecting is what touches the bed of the 3d printers They're all they're all flush and flat and level But schools that you can see here with this section analysis Tool you can turn on and see a cross-section view of the hinge and see what it looks like Slice through the hinge. So you hear that there is some clearance between the surfaces and Really the magic number here is the clearance number. It's a quarter of a millimeter So point four millimeters is the distance between any of these surfaces, right? So if we click on this surface and this surface here, you can see that yep point four millimeters is the is the number same thing with the With the kind of cut out here the cylindrical cut out So if I select that surface and then the surface here point four millimeters So again point four quarter of a millimeter is kind of the magic number for clearance So let me go ahead and turn off the section analysis and then turn off the handle itself So you can just see the hinge itself, right? so these are kind of the hinge pieces and They print without any supports now this cylindrical thing that is going across is Rather short right the length of this or rather the the distance between this surface and this surface is About ten millimeters. It's a little bit more than that, but that's because of those offsets, right? So if we bring this into our slicing program You can get a good look at what it looks like when you when you 3d print it and take a look at the layers So as you as the print is happening. It's creating these little tabs It it creates this bridge right here, and this is the first layer That creates that bridge and because it's a cylinder it'll start Gradually so it'll start with one line and then just a kind and then just kind of advances and creates that circle shape So you can see here that it's definitely geometry that a printer can make However, you want to be careful of how long this thing is if you go any longer than I think maybe 20 millimeters You're gonna start getting some droop and if this bottom here starts a drooping well Then when you start articulating the handle bit you're gonna Catch some of that material and you might even hear some crunching and it might just mess mess up the the articulation of it so I Say as a rule of thumb maybe stay in between 10 and 20 millimeters of distance for your print-in-place hinge So that's just what I found it could be different depending on your on your project But I found that let's keep it around 10 millimeters or less than that or more, you know less than 20 but at least At least 10 millimeters. So that's why I haven't set up here So those are the hinge pieces in a quick look at kind of how the layer structure set up So then when we bring the handle back in and if I hide the hinges you can see here that the handle piece is really simple It just has This kind of shape and then it rounded these surfaces get rounded off or rather these edges get rounded off And then there's a circle in the middle here that allows that That that hinge post to kind of flow through there All right, so with that I guess we can start designing it up I'll take that back So I another sweet thing about this is that it's driven with user parameters, of course, right? So with that you're able to modify some of the aspects of the design like the Like the thickness of the handle, so let's say I want a thicker handle, let me say I want 15 millimeters You see that it grows it up pretty good. So they just got chunkier Let me bring that back down to 10 and then you can play around with the length of the handles Let's say I wanted a little bit shorter So half of a of a hundred is 50 you see I got a really small hinge there or a really small handle Maybe you can make it really long say 200 and that goes long And then there's this other one here called the grab. That's basically like the amount of Distance you have from the handle bit to the hinge bit So if I just modify it you can see here what it's doing So I put 80 here and you can see here that yeah, that just makes it longer Maybe bring this back to 100 Back to 40 you can see that's working pretty good So yeah, that's that's those are some of the user parameters that it have set up It was really important to have this because as I was designing the handle to fit the the pico fighter Projects I needed to kind of have that be scalable so I can play around with the proportions because that I didn't want the handle to be too big Or too small so that's why it's important to have a user parameter setup so you can play around with those Proportions once you've got these two designs together. So with that, I think now we're ready to actually start modeling it So I'm making new tab here Let's play around with Making sure that our layer structure is correct. I'm gonna create a new component and I'm call this the handle assembly Because that's what's gonna have my my components inside there. I want to have a hinge So I'll have the hinge set up and then I want to create another component But I need to make sure that the handle assembly is selected so I don't make a component inside the hinge So we make a new component with the hotkey n That's the hotkey that I have set up and then this will be the actual handle bit that you grab And that'll be that so those two right now. I have the hinge and then our handle So let's go ahead and activate the handle assembly Which is like our main route and start with our sketch so our sketch is going to be on the floor here and Before I start sketching let's go ahead bring up our user parameter window and create our user parameters so I'm gonna have a user program called wall thickness, which would be the thickness of the kind of Mounting brackets for those mounting holes So I'm gonna have that be two and a half millimeters and we can adjust that later if we want Next thing I'll do is the handle thickness. So the thickness of the handle that will be 10 millimeters I want to be around number like that. That's pretty even Okay, so handle thickness another is handle length. So the length of the handle. Let's go ahead and make that 100 as well Handle grab which you saw me Test I'll have it set to 40 And I think that'll be it for now we could do things like mounting holes as well So like the mounting hole I Could do that I put 3.2 because I like to use m3 screws that point to gives me a little bit so I can pass The screw through easy All right, so I think that's it we can always add more as we need to all right, so to create the handle Or rather the hinge is really what we're gonna draw first So I want to create a line That'll go across like this and I want the length of that to be the handle length, right? So that's the length of our handle hit okay So this is a free-flowing line and what I want to do is make it symmetrical with the center of our grid Which is this guy in the center so with that dot selected I can hold down the shift key and then select this line Bring up my my sketch Shortcuts which is the hotkey s and then I could select or type in midpoint I already have it added here You can add things here by typing in one of the things that you'd like So like I said mid and then you can hit this little icon here now I already have it there so that's why it's an X That's if you wanted to remove it but that helps me quickly pull out things that I use often like well these right here So the midpoint that's what I want and then that's what It snaps it right into the middle. So now I have this Now I don't want it to kind of cut anything so I'm going to make it into a construction line So I really just need it for placement So with the line selected hit the X key or this icon here This is line type and you can make it a construction line there. So that's cool All right next up. I need to create the The the actual hinge bit so this I'm going to kind of draw separately and then place it later I really like that method of drawing your thing first and then placing it later So I'm going to start around somewhere around here. It needs to be kind of a rectangle shape Now I know that the width of it or rather the yeah the width of it needs to be the handle thickness So right here. I can just say I want that to be the handle thickness Okay Now for for the length of this is going to be a little bit different So I'm going to have a fixed value for now. I'm going to make it 32. Okay Next thing I want to do is I need to figure out so I can move this rectangle around now Okay, that's good to know I can move it around and as I drag these corners It'll snap it to the grid. That's another behavioral thing. That's good to know So the next thing I want to do is create a line a center line And as I roll over any of these edges You can see here that this this triangle shows up and that lets me know that's the center So right here center of that line center of that line just by rolling over it kind of snaps into place as well So what I'm going to do is I want to have a line that goes from this middle point To the bottom of this middle point cool, and that lets me create mirrors of things now again I can move this around I'll just move the corner so it snapped into the grid and what I want to do is with this line Is I also want to create a construction line because right now I can select two profiles of this rectangle I don't want that so I'll select the line hit the x key and that Blocks that makes it so you can use the line, but it's not intersecting it and in these the shape The next thing I want to do is I need to create those holes those mounting holes They're really important because otherwise I'm not sure how else to attach I guess you could glue it So maybe you could do that but what I want to do is to create this line that goes in the center here Rather a hole So let me use the circle tool So you can use The midpoint to kind of place it, but it doesn't really matter So let's say I want to place it here And I want that use a parameter of of hole right the mounting hole And for whatever reason it's Hugo Mungus. What happened there? I thought it was yeah mounting hole. I guess I just didn't type it right So there you go. It's 3.2 millimeters and it's it's free right I can move it around But what I want to do is I want to create a line that is in the center of the circle And I want it to be in the middle of this thing, but I want my line to be straight Well, I can't quite do that yet. So let me place it first So you can see that there's a there's a midpoint constraint going on there So that's in the center of that And all you do is select this line and and apply a horizontal vertical constraint And that'll just make it so that it's always horizontal or vertical So now what I can do is I can add a distance from here Let's say I want four that seems to work. Okay And then what I want to do is grab that line and then also turn it into a construction line So I'll select it and then hit the x key. So now Um, it's just this right here Cool. So now I can move this whole this whole group of of of shapes move it around And really kind of create a mirror of this hole because I need another hole on the other side So now that it's all drawn up and it has like all these fixed numbers I can hit the s key Hit mirror That's my object that selected in my mirror line hit the select And then this will be our mirror line here this line that we made earlier and then hit okay So now you can see here. I have like my whole group here So now the question is how do I place this? How should I place this with this line here? Which is defining the length of our handle Well, I select this line, which is our kind of our construction midline and then I select this Dot right here this point And then what I can do is I can say well I want to have a midpoint constraint between those two and that will snap it into the middle now So now I have this This piece here that um that I can use Or that's set in place rather. Sorry Now what I need to do is to create some walls some lines that will become walls, right? So what I'll do is I'll grab my line tool and then I'll start from somewhere around here And then just go straight down making sure that it stays Um perpendicular with the line. So now it's straight across So I can move this around and what I want to do is I want to have a distance from this line to our center line And what it should be Is our handle thickness So I can type in handle thickness But I actually want to do half of that So divided by two so just put a slash and then two and that'll take the thickness of the handle and divide it by two And that makes it five. So there we go Now what I want to do is I want to create another line right here That will also be perpendicular But I want to have a distance of these two lines What distance the wall thickness. So remember we set up our wall thickness. So I'll put that in here And now that's set up. So now I have this this little sliver Of of of shape that I could extrude out and create a wall But I need another one on this side. So instead of drawing it another set of lines I can just select these two lines Pull up my sketch toolbox hit mirror Select my mirror line, which is this guy here and then that'll make a mirror of that So you can see here now I have all my elements. I have like my base here Okay, I have my wall here and my holes here And it's all set up so that if I ever change the thick the length of the handle The placement and position of these sketches will go with it. So let me test that out So as I go, let's see 50 it brings it inwards if I go back to 100 It'll pull it back outwards and it's all flowing with each other And that's what we want All right, so that's pretty much the first kind of sketch A little bit of a lot of lines, but they make a lot of sense When we start doing it. All right, so hit okay Next thing I'm going to do is select the hinge We need to make sure to select the hinge component because that's where we want to create If you don't select the hinge component, you'll be making bodies inside the handle assembly So it'll gray out our sketch, but that's fine We can still select these elements or these shapes And as I'm holding down the shift key, I'm selecting multiple Multiple profiles here So now with those selected I can say extrude and I want to start extruding this out This will be the wall thickness. All right That's two and a half millimeters and that's what I want. So I'll hit okay Okay, the next thing I want to do is create these walls here All right, so I got these walls here And with them selected I'll again hit E for that's the hot key for extrude And the distance here will be our handle thickness All right now because it's Starting off the bottom of our grid it wants to cut as the operation So you can just change that to join and that'll create what we want So we want that 10 millimeter handle thickness And I'll hit okay Now one thing that we don't need is this this surface here So instead of adding a whole new thing, I will go back into the first extrude And just hold down the control on windows or command on a mac and deselect this middle one So now you'll see here that I actually have two separate pieces here And that's what it um, oh I need to make sure that this joins There you go, and now it's joining these two together. So now you have these two separate bodies So if I bring the uh The component opiate here. Yeah, I got those two separate bodies So we need to bring them together now with that pole that we're going to create So I'm going to create a new sketch inside the handle assembly So let's highlight the handle assembly And let's let's go ahead and name this this will be like the hinge base And I'm going to make a new sketch, but this time it's going to be on this side Um plane here. So this side plane on the left and the right I'm going to hide the hinge base so that so it's not in the way and then I need to create a circle Right somewhere going down this the y-axis here or maybe it's the z-axis and this will be a fixed number Right now I'm going to make it four millimeters So there it is, but it's free so I can move this around What I want to do is I'm going to make make sure that it has a line That connects to the center of the origin so right here Like that I'll hit escape And then what I want to do is apply a horizontal vertical constraint to this line So it's straight up and down And now what I can do is I can apply a dimension Uh To this line, so I'll say I want this to be the handle thickness, right? So the handle thickness is the value that I want it's 10 and um You'll see here that it pushes it all the way up I want it to be the half of our handle thickness So all I need to do is to go in there and say divided by two slash two hit enter And then that gives it that puts it right in the center here where we want it All right, so that's pretty much what I want hit. Okay Now with that I can select make sure you select the hinge, right? We we're going to start applying stuff to the hinge So I need to make sure the hinge is selected. That's the component. It's active graze out our our little Um our sketch, but that's fine I will now select that and hit e on my keyboard to extrude and what I want to do is I want to say start I want to start this from this surface. So now that it's set start object I need to select the object. So it'll be this surface And then the direction will go Um Sorry the extent type will go to object and now it wants me to select the object So of course, I'm going to select this surface here and you get a little preview And it even tells you that that's that distance is 10 millimeters and that's what I want But it's parametric. So if if the distance ever changes i.e. the handle thickness, it'll it'll change with it So I'll hit okay. Make sure the operation is set to join And now it'll join those two to make a single body here. So now I have this This um the single body here There are some things we can do to make it look a little bit better and to make it more structurally kind of Better. So what I'll do is I'll hit Draft so I want to draft these these Faces here, but I need to select my pole direction first Which will be the top the tip of this here the top surface and now I can select my face here So what I want to do is I actually want to bring this out a little bit And what that's doing is that's giving us a little bit of a draft so that The wall is a little bit more Rigid when it prints and you can select the other and to the other surface and that just gives it a little bit more Um a little bit more geometry to work with All right, some other things you can do is some fillets. So if we want to round off these edges here There's four here at the top that I can round off You can see here Instead of putting a fixed value why not give it the handle thickness because that's uh That's what we want to divide it by two because it's a fillet and the fillet is a radius not the diameter So you can do that by just putting divided by two and then I'll also select these edges here Which round that off and that looks whoa. Whoa, not the surface. We want to select the edge And you can see here I'll select this edge here and that gives us eight edges to work with So now I have our hinge. Look at that now one thing to note is that look at the clearance between Our hole you can see here that You want to have enough Area here so that your the head of your screw Can fit in there depending on how you're attaching it, of course If you don't have screws and you just want to glue it to something you wouldn't even have holes But as long as you have some material here you can attach this to something else, right? So there's that there's our hinge Okay, the next uh, I think the next stuff we want to do is to Is to start making our handle bit All right, so with that I want to make the sketch for the handle inside the handle assembly as opposed to the handle component So I want to name this sketch to uh to like hinge Post or pole something like that. I'm sure there's a better name. Maybe the pin Hinge pin or something like that would probably be better So again, let's let's let's uh highlight it activate it And now I'm going to draw so I'm going to draw again on the on the floor plane here So create new sketch make sure handles handle some handle assembly Is selected here and then I can uh select the floor plane here. All right That's correct. Yeah All right, so now what I want to do is kind of create A line just very similar to what we did before I'm going to make it uh go this way I go down And basically I'm just sketching out the rough kind of um Lines that I'll need to create a handle, right? So I just sketched it out. This is kind of the general shape. It's not flowing yet But here's what we'll do. All right, so we know that this right here This should be the thickness of the handle so I can apply a A dimension and then use the handle thickness parameter. So that's how thick I want that But also this right here this these two lines They should also have the thickness parameter. So I'll apply that Okay handle thickness not the wall thickness All right, so I have that set up Now That's cool. I can move these around now and and most of these will we'll have a consistent thickness to it, which is good But what I want to do is I want to start with this line So I want to say this edge needs to be a certain distance away from the center of our origin. So I'll do a A dimension So what I'll do is I'll say We want it to be the length of our handle, right? But I need to divide that by two. So let me put divided by two. Let's see what happens, right? Fusion has to think about it. You'll see that it's almost there It takes that but because we're selecting this line You'll see that it's in the center Of our of our hinge So then all we need to do is say well now that we have that let's put this in parentheses Okay, that little equation and say, you know what? Let's subtract it By the thickness of the handle But the thickness of the handle needs to also be divided by two, right? So I'll put that inside another set of parentheses and then handle thickness divided by two And then that gives us this number here 45 Which will change now depending on how we change the thickness So let me open it again. You can see here the full length of the equation is we're taking The handle length divided by two subtractive by the handle thickness divided by two All right, and that's what gives us the placement here the perfect placement that we want now this right here This needs to also be a certain distance away from our center origin Going on this way How much? Well, we take the handle thickness and we divide that by two And that will place it right where we want right there So that's how we're able to use our user parameters to offset the placement of our lines Now the next thing we need to do is how much how much distance do we want from this line? To this area here, so what I'll do is I'll create a line That will connect And as I roll over I want to pick the midpoint, right? So here's the midpoint and then I want it to to land right in the center origin But now with this line, I need to apply a horizontal vertical constraint. So select that All right, and now I can apply a dimension to this line Um, I think it was 40, but it's also a user parameter, right handle grab So that's what I'll put there Cool, and it can be a construction line as well. So I'll select that Hit x key and now it's a construction line Cool All right So really the next thing is to you'll see that this line here doesn't quite have a A symmetrical relationship to this line. So I'll do another line Roll over find the midpoint And then land it on the midpoint here down below and then apply a horizontal constraint to that Just like that again make this into a construction line So now I have these lines that won't move. They're locked in and fully constrained But I need to now Should I draw another set of lines on this side? No, we have the mirror tool Which which is awesome. So I'll select these three lines this one This one and this one Hit the s key hit mirror Select my mirror line, which is it could be any of these lines here this one or this one But I'll just select that one you get a little preview hit okay And that's pretty much our whole handle that we need In this sketch here. So now I can name this sketch like handle profile There you go, I finished sketch. So that's what we need Now I have that I'll select the handle. Remember we got to select the handle activate the component And then we can select our profile here the handle profile Hit e extrude and that will make this the handle thickness So use a parameter hit enter and there we go. There's that piece there All right. So now that we have that we need to create a a hole For this But not yet what I want to do is start to add A little bit of offset. So I'll select the main component here And what I'll do is select this Right here this surface hold down shift and select that surface too and we need to push it back By the value of our gap. We need to push it back So what I'll do is with those selected I'll hit the q key and that gives us an offset that's offsetting the face I'll set the type the offset type from automatic to new offset And then here in their distance. I'll put negative and then spell out gap Now I didn't add a gap yet, which is which is a problem. So let me hit cancel Bring up the use of parameters and type in gap and this will be that quarter Of a millimeter zero point four millimeters And that'll be the gap distance between all of our surfaces that we need to do in order to have good Tonches and to prevent our parts from fusing together when they're 3d printed So I'll select this surface this surface q is the hot key Offset is new offset and then the distance is negative gap because we want to go on the inside And then you can see here that it's given us that little bit of if gap. So hit okay Now the next thing I want to do is add some offsets to our hinge Here so if I hide the handle, I need to select this surface Hold down the shift key and this surface With those surfaces selected I'll create I'll hit the q key Which is the hot key for offsetting the face the offset type is already set to a new offset and now I can type in here A negative gap again, and that's our negative point four. You can see here as I hold down The control or command key you can you can see how much it's affecting it. So that's that negative 0.4 millimeters pushing it out Okay, so I'll hit okay to pen that or the enter key and now when I bring back my handle You can see that. Yep. That's the distance that's the distance that we need Okay, so with that now I need to create the hole. So if I hide the hinge You'll see that I don't have a hole there yet We already have one the hinge pin is the sketch that we can use. So I will Um highlight the handle because I need to activate that component in order to mess with it Select this circle here Hit e for the extrude and then basically you just pull it out I can just pull that out and what I want to do here is it's a little bit of a smarts here. So for the Direction, I want this to be symmetrical. So that's easy and then for the the extent type I want that to be all so this will go through all visible bodies here as it says And that's parametric now. So if I ever change the length of the handle It'll remember that the extent type is set to all so it'll always go through the whole body. So hit okay Um, I probably should have said that that's a cut It is a cut already because that's what we want to do. We're creating a cut okay But because that hole is the same diameter as our pin We need to select these surfaces hold down the shift key So you can set both of them and then again, we'll do another offset with the q key Um new offset and this is going to be negative gap and you can see here that it's uh pulling it back opening that that hole by 0.4 millimeters All right, and that's what we got a hit. Okay, if I bring back the hinge You can kind of see that. Yep. That is what we want. You can see that there's there's definitely clearance between those And at this point we can select the whole root of the document hit section analysis And then select this surface here to get a cross-section look at it And that's pretty pretty much what we want right there cool At this point what we can do is do a mirror of our hinge now so i'm going to hide the section analysis and Go inside of the handle assembly Bring up this the design shortcuts do a mirror And make sure our type is set to components select our hinge And then our mirror plane will bring up our origins and i'll use this this this plane here to be our mirror Plane and then you can see a copy here of the hinge and hit okay, and that's uh, that's our two hinges now Now the The handle is very blocky. We can we can make that much better here So what i'll do is i'll add Some fillets to these edges here. How much? We should probably drive it parametrically if you want that full roundedness Let's take the thickness of the handle and divide it by two Let's go ahead and select the other side as well these these two edges here real nice okay And then if you want to add fillets to this corner you can do a little trick here as well So let's say i want these inside corners these inside edges to be like four The outside edges if you want to add a nice consistent, um fillet to it you would add four plus the thickness of the handle and that gives you um 14 And i'll uh held down the command key on a mac or control on windows to Select the second edge there and you get this nice rounded edge there. It's consistent So it looks good and one of the last things I did was just apply a chamfer to the edges here So this edge here and this one here just add a one millimeter chamfer and that makes it look nice All right, so now if we try to move it you can see here that it just kind of you can just drag it in space So if you want to apply joints to it to simulate the articulation pretty easy to do so so, um, I'll select, um You kind of want to be able to see what you're selecting So i'm going to hide the hinges for a second and just focus on on this This is what I want to apply a joint to so if you've never used joints Uh, it's under the assemble window here. The hot key for it is j. So i'll select that And the first thing i'll select is um, you see that when you roll over this cylinder You see that there's these little, um, these kind of these little snap points and the way to get to them is to hold down command on a mac or control on windows And when you hold that down you can now kind of select It locks that selection of the surface and now you can select one of these snaps I need I want this center snap. So I'll select that That now graze it out and gives you this little cookie icon Now what I'm going to do is bring out one of the hinges Okay, so this is the hinge that I want to use But I can't see it. So I'll hide the handle And then again if I roll over the surface And hold down command or control you can snap to one of these guys So I will of course I want to snap to the center of the cylinder Now I can't see anything yet. So I have to turn on the handle again But that's it. I don't have to play around with any of the alignment for the joint here because it's pretty much In the center that I want But I do want to go into the motions tab and just verify that the type is set to revolute And that the rotate is on the z-axis and then this little animate lets you preview The animation and that's what we want. So that that's great. So I'll hit okay That works nice give fusion a second. I can bring back the other hinge Now it's not going to work though. It's just going to go with it because there's nothing really Grounding our hinge yet. So I'll hit You know hit control z or hit revert up here And what you want to do is select this handle right click and you see that ground if we hit ground It'll pin it basically saying you're grounded. You can't move So now it can't move but if I move the hit if I move the handle It allows me to to articulate it. So that's cool. You'll notice that I didn't need to add a joint here But if I move this one, then yeah, you need to you need to apply a joint there. So you can do that Again, it's super easy. Just kind of want to be a little bit careful. So I'll hide the second hinge Come down here Hit j on my keyboard Roll over the surface hold down command or control and then select that middle point Hide the handle bring back the hinge Roll over the surface hold down control or command select the midpoint bring Reveal the handle again and just verify that your motion is set to revolute in the axis of syphus z and you can preview it again Hit okay So now that works as I move it though, you can see here that the You know because It's not grounded. It's moving freely. So that's easy to do Undo all that right there right click on your hinge that's mirrored and then just say Ground and then there you go. So now you can move this stuff around All right. So that is how you design a print in place handle now. Let's play around with the user parameters Let's say I want to go thicker here and go with 20. What happens? It goes really really big now. Here's the issue with the thickness Because the length the width of our hinge Wasn't really set to be parametric. So if I bring up the hinge base Right click and say show dimensions You can see here that this 32 Should probably be a user parameter. So let's say we want this to be the thickness of our handle plus Let's say 25. What happens there? Well, it gives us no matter how Thick the handle gets That that fixed value will always append to the width of our hinge So if I go a little bit lower here, let's go 15 You can see here that's probably working a little bit better 20 that's working a little bit better And you really want to be conscious of the clearance for your mounting hole If you are using screws, you do want to have at least a little bit of extra room here for your screw head the head of your screw So you want to add more to this like 30 That's fine too. It really depends on your design and how how You know, how do you want it to fit? All right. So then the handle thickness will go back to 20 And here that's that's not that's working okay as well. So that's a really chunky handle. That is super huge, but it still works It's just an extreme example of showing how the user parameters can work Through across the entire design if you take a look at the timeline, there's not really that much going on there I will have this as a downloadable thing. So folks can customize it and step through it But yeah, that's how you can design it. It's really simple if you wanted to add more things to it Of course, you can add more pieces to it But for this one, it's like the most simplest that I could come up with And it worked out really well for for the pico fighter Because it's it the simple the simplicity of it Really really looks nice with the rest of the kind of the the rest of the simpleness of the of the case Now I have another layer of a layer. I did a couple A couple maybe a year ago on how to do a print in place Hinge with a door. So here's one that I did Like I said a couple maybe a few years ago So there's another example. I'll have that linked as well And just for extra credit stuff I have a crank that I've also done that I'll probably do if you guys want to see that let me know I don't have it here open, but that's pretty much what I wanted to create Yeah, let's go ahead and look at You know at cura at slicing it real quick. Now we looked at this hinge, but let me bring in The whole thing so you if you're wondering like how do I export this out of fusion? You would export this assembly as opposed to each individual body as an stl You just bring in this whole thing right click save as stl Hit okay, and then save it where you want All right, and then that'll come in to your slicer Like this so bring it in There it is in the right orientation that we want Now let's slice it and then we'll step through the layers in the preview tab here. This is cura So here we can step through It's only 50 layers tall And you can see here that yep, you can see the clearance down there And there's a good amount of clearance that That does not fuse at least with my setup It's a 0.4 nozzle with a 0.2 layer height and the line width is 0.38 If that's helpful for anybody, but it's going to be different per printer But you know that's a good kind of look at just stepping through the layers making sure that your offsets are all there and everything and that your You know your infill is where you want it to be at the infill here is like gyroid 10% But that's going to do it for this one. Let me know what you guys think if you guys think that's a good idea If you print it out do let me know Hope you guys like this one. I will see you in the next one, but until next time remember to make a great day. Bye folks
