 Last week we looked at creating this model here which I 3D printed, came out really beautiful but some really valuable Fusion 360 techniques here that I showed. And so the finished product is this here where we have this container. And you can see it prints in multiple pieces here. So three separate bodies, the container part with this Greek and lay pattern here. And so here's the pattern that we made and we have this lid that I 3D printed from with PLA. It came out really nice and really perfect fit onto it. So last video we ended, let me take this timeline back right here. So this is where we kind of left off where we only had two bodies here. And I showed you the main tutorial there was showing you how to create this inlay pattern to give you a perfect wrap around a cylinder. So it's a really great technique there that I showed. If you haven't caught that video yet make sure to check it out. It'll be the video before this one on my list of videos. So check that out first and then come back here because we're going to continue this design here. So let me take this timeline and bring it back to the end and you'll see where we are now. You'll notice this key pattern here is now flush with the container here. So I'm going to show you how I did that. And you also may have noticed some chamfers here, which is a really, really great strategy to apply to your parts when you're trying to avoid printing supports. And just some techniques I want to show here, especially in creating this key pattern, that Greek key pattern here. The approach that I used to get that to fit onto this container here. Remember we're talking two cylinders here. So how to get this to be able to just snap into place. You'll notice here if I zoom in we have a little gap in between there to allow that to snap. And there's also a slit here so that when we do 3D print this we can sort of extend it over this container and allow it to snap into place. And the other big part is you'll notice here that I've got my own support structures that I made. And so this was from printing this using regular slicer supports and they were just a pain to remove. And I thought this was a great application that you can use to create your own supports in Fusion 360 and make it so much easier as you can see here to remove this, remove these supports. So I want to show you the techniques that I used there. You can see here that these supports don't connect to these edges here and there's a really easy way in Fusion 360 to be able to generate these. So you want to have these, the strategy sort of in your back pocket when you need it because it really comes in handy. So I've got, it's a bit of a long video here but there's so much gold here that you're going to want to stick through the whole thing because these are techniques you'll be able to use over and over again. That'll really make you just a very efficient designer when you're trying to make something like this. Okay, let's jump right in and continue with this project. Before we do that, just a huge thanks to my Patreon supporters. It really allows me to be able to set apart some time and dive deep into these tutorials for you. So again, thank you and if you are not a Patreon supporter and you enjoy my tutorials and find them valuable, I do have a link below where you can join. And in addition to these YouTube videos, I also post other tutorials to my Patreon page and sometimes I dive deeper into these projects and explain things in a little more detail. So you'll have access to additional tutorials there and projects that I do. So link is below. Really appreciate all the support. And again, huge thanks to my existing Patreon supporters. You guys are amazing. All right, let's jump right into this design. All right, so here's where we left off last time. So we've got two bodies here, our lid and our container. And we see here that the container and the key pattern is still one piece. And also the key pattern here is outside the container. We want something like this, or if I bring the key pattern and it's flush with that container and we can print them separately and they can just snap in. So let's continue with that here. So the first thing we need to do or the next thing we need to do is separate the key pattern here from the container. So we have two separate bodies. There's a couple ways to do that, but what I'm going to do is take advantage of my split body tool here under the modify menu. So modify down to split body, I'm going to select this body here and now I need to choose a splitting tool. Now the splitting tool I would want would be this face here or maybe this edge here. But it's not going to let you select the same feature from the body you want to split. But we can select the sketch here. So actually our first sketch, sketch one if I showed that, that gives me, let me just untie it so you can see it a little clear here. Let me untie the body, sketch one, that's where we created that circle. So if I bring back the container, you can see it right there. So this circle edge here, I can reference that from the sketch. So what I'll do is let's go back to modify, down to split body, body to split this container, splitting tool, as long as we have that sketch turned on, we can select it here. You can kind of see it highlight blue. It'll extend that, it's the splitting tool up if we have this checked and it will click okay. And now we should see that we have two bodies here, the key pattern by itself and the container. So that's the result we wanted. And we're going to have to rename these. So the container is already named container and the key pattern we'll call that key pattern. And there we have it, quick and easy way to split this. And so the next step now is we want this key pattern to be inside the container. So basically we want to end up where we can cut one piece from another but it needs to overlap the same area. So here's how I'm going to do that. Let me untangle the container there. And I need to basically extend this face inwards and then also extend the outside face inwards so that it occupies more interior space here. So to do that we'll go to modify and we're going to use our offset face here. And then I'm going to choose the inside face. I'm going to go in two millimeters and now I'll have to do the same thing with the outside face because now this is a total of four millimeters in thickness there and I want it only to be two. So let's just repeat that offset face. I'll select the outside and here I'm going to do a negative two offset. And there we have it. Now we can see that they both occupy that same space. So we brought that in two millimeters. All right now that we have that the next thing I need to do is to perform a Boolean operation to cut this key pattern to leave us with the hole here to be able to snap it in so we can actually perform or have an inlay and print them separate to be able to snap the key pattern into place. So to make that cut I can go right now and do the Boolean operation but if you take a look here let me actually this will be easier to explain if I show this design here. If we take a look at the finished design here you can see this edge here this one and this one they would give us issue if we're trying to print those right let me actually I have a chamfer on there now I'm going to go to the timeline here and I'm going to just find that chamfer and suppress it. So you can suppress it. Now we can see that these straight edges here if we try to print those right this is an overhang couple of issues this is curved and also this is way too long to bridge and the way we can solve that is by just applying a chamfer so we would need to apply one to that surface this surface and this surface here and that would allow it to print so applying chamfers is a great way to avoid having to use supports when you're trying to 3D print your parts. So that's exactly what I did here let me go back to that timeline and unsuppress so we see that chamfer being applied so that way I can at least not have to print supports on you know one of these models here but to apply the chamfer here's what the approach I'm going to take instead of doing the Boolean operation and then applying a chamfer because then I would have to do it to this surface and also to the key pattern here so it would fit instead I'm just going to do it once and I'm going to apply it to the key pattern here and then create the Boolean operation and in that way the the container here will have the chamfers already applied so the way you have to kind of think about this is almost an opposite terms because we're going to apply it to the key pattern and then it's going to be subtracted from the container part so here instead of applying it to the parts that we would think of in the container which would be these top faces here we're going to do the opposite so it'll make sense once I actually do it and you'll see it so let's go ahead and go to modify chamfer and I'm gonna select all these interior bottom edges here and I did try doing one set and then doing a circular pattern of all of them but for some reason I wasn't working with chamfer so instead we're gonna go ahead and just do it this way actually let me just do all these edges so you're saying I'm doing the the bottom and then the middle and then the top and these are the the top edges of the top faces so the interior tops so we select all of them here so you should see we have should have a ring around that bottom the middle and the top and now I'm gonna do a 2 millimeter chamfer there click okay and you can see all these are chamfered okay now that we have that chamfer I could bring in that container and then we'll go ahead and go to modify down to combine and we're gonna change operation here to cut target body is our container tool body is our key pattern we want to make sure keep tools is selected otherwise it'll delete the key pattern there as our tool click okay and there we have it now we can untangle the key pattern and we should see that we have these chamfers all automatically applied here to the container which will allow this to print with no supports okay so that's that and the next thing we'll need to do let's bring in the just the key pattern here if we want this to be able to snap into place we're gonna have to apply an offset here so that the key pattern is just a little bit smaller than the container so to do that we'll go to modify down to again offset face I'm gonna select everything oops if you ever get this lasso select just change it from the freeform selection to window selection here and then we'll draw a box around the entire model here and then I'm gonna hold the control or command button and unselect the front and inside face so we just have the these inside edges here selected I'm gonna do a the distance here an offset of negative 0.1 and there we have it now if I bring in that key container you should see that if you zoom in there's a little gap between the two bodies and that's exactly what you want so that will allow this to snap fit right in okay so a couple more things we need to do here let me untangle container we want to be able to print this and this is gonna be a nightmare to print and as I showed you know we could automatically generate supports but it's gonna it's gonna be a lot of supports and it's really gave me a hard time I did try that first and it was a pain removing them so I said you know what let me try to create my own supports here I think this is one of those examples where modeling your own supports is really the solution here so what I did was I want to just create some pillars here to support this and it's just the very strategic places so let's go ahead and do that I'm gonna create a sketch on this bottom face right here and orbit so that we can see it and now I'm going to project so P4 project here let me untangle these other sketches P4 project and I'm gonna select I've got specified into these specified entity selected I'm gonna select this surface here it's gonna give me an outline around it so now I can untangle the key pattern body and I'll just have this and here what I'm going to do I'm gonna draw a couple lines here so one line here and go ahead and make sure you move it so you're not getting it to snap and give you you can see here I've got a vertical constraint there in blue I'm just move it till you're not getting a constraint being applied and I'll do the same thing to this side here so you got a parallel constraint and then a vertical just move it so there's no constraints there applied and now I want to set a dimension between these two but notice if I click this line and click this line here and I do a dimension it gives me an angle because they're not parallel so what I can do is come here grab my parallel constraint and make them both parallel and for some reason it throws it here to the side we can just drag it back in so now I can go ahead and select these two and give it a dimension and it'll let me do that so I'm using your constraints here really comes in handy I do have a free constraints cheat sheet which you can find linked below which describe all the constraints and what they do so make sure to check that out if you haven't yet I'm gonna do the same thing with this other one here I'm gonna grab my parallel constraint make them both parallel and then if you don't see it because for some reason I want to drag it away and just bring it right back D for dimension and then we'll go ahead and dimension those and I'm also gonna do an inside one here for this one I won't worry about making them parallel I'm just gonna draw these two lines here again I'm not gonna snap a constraint here because it'll lock it into place but if I want to do a dimension in this case because I can't do these two lines because they're not parallel I can I can do point to point and it'll let me actually let's redo that because I want to show you here you can do depending where you drop that dimension you know you've got a stray and you can it gives you this sort of parallel but I'm just gonna do it from here to sort of straight line there and do five millimeters and then I can move these in you know and then you can also it lets you like you can adjust these if you want so if you didn't want them to be parallel it's it's not crucial that exact angle but maybe we'll do something like this and then if I click these I can just drag them in words so okay I just kind of wanted to show you that and that distance looks good to me here and then what I can do is I'm gonna stop sketch here or finish sketch bring that sketch into view let's also bring the key pattern body into view and then so here's the magic here and the secret sauce of creating these support structures I'm gonna hit E for extrude I'm gonna select these three profiles here and now what I'm going to do is extrude these down to this surface here so I'm gonna choose extent type I'm gonna go to object selected this chamfered face here it's gonna go all the way down and instead of start here at profile plane I'm gonna choose an offset and I'm gonna give this an offset of 0.4 millimeters and did you see what happened there so now you turn here it didn't start it right from that plane it gave me a little gap there of 0.4 I'm gonna do the same thing with the bottom here watch what happens maybe it'll be easier to see if I look from the inside here so you'll see I have another offset here right under the extent type and I'm gonna make this 0.3 millimeters and you see there now that actually let me it would have been easier to see it from this angle here so let me just orbit me bring that back to zero keep your eye on this part here it goes straight to that that bottom surface that chamfer and I will do 0.3 it backs it up 0.3 so the reason I'm going 0.3 is I did try both of these as 0.4 because this is chamfered it didn't stick well in some cases to it so I just backed off a little bit made it closer to that edge and at 0.3 it worked for me where these pillars actually stuck so the key here these numbers I'm giving you really worked well for me so save you the step of having to kind of go back and forth and an experiment it allows it to stick where it'll support it but it doesn't fuse to the part so that you can easily commit and just break them so that's where that that getting that gap right you know is is is important there so if you do have to tweak it'll probably be like within like 0.1 millimeter one way or the other but that's the strategy here that I'm using to create my own supports and taking advantage of these options here from starting from an offset and adding that offset in there is really the way to go and I'm gonna do the same thing here with the top surface here so let's really quick just create a sketch here and what I'm going to do is I'm gonna project at this surface here so if I click people project notice I highlight over here it's gonna give me a line on the bottom there showing me where that meets and then I'll just create another line here right there you see these two lines and I'll dimension these from point to point it's orbit so we can see I'll just do five millimeters there and then since I didn't make these parallel I can just adjust this angle not crucial finish that sketch I'll do the same thing extrude let's flip this around so we see it do it one more time start is gonna be an offset that offset is gonna be 0.3 millimeters and extend type to object I'm gonna extrude to this chamfered surface there and that offset is gonna be 0.3 it's gonna back up and that's exactly what we want so now that we have these three support columns here what we can do is create a circular pattern so we'll go to create pattern circular pattern I want my pattern type to be bodies and the objects are going to be these three bodies here my axis of rotation I'll just select this bottom circle edge there and I want six of those so we'll go ahead and click six change the quantity to six click okay and there we have it and you'll see because these aren't attached these come in as all separate bodies okay and then if you want to you can untangle all of these but here's a shortcut if I right-click on keypad and I go to isolate it just gives me that one object and then I can bring in the lid in the container and I have that here okay and then finally throwing a lot at you here fell out of really good stuff the last thing I I did was just put a slit in the middle of here because in order to get this to fit around a container I have to kind of stretch it over and bring it in and bring it you know together to actually snap into place so what we're going to do is I'm going to create a sketch on this bottom surface here so create sketch right there and then I can just come in and again project this face here because I want to extend that line to where it meets right here so P4 project select this face and I get a line right there and what I'm going to do here is just draw one more line again edge-to-edge and I'll go ahead and actually make these parallel and drag this back and then I'll do a distance from these two lines as 0.2 millimeters and there we have it finish that sketch and now I need to bring it back into view here now I can simply select this face there that profile bring it up extend type change that to all and that'll put a cut right through there all the way up and here the key there is it's the same principle these don't meet so they're not going to completely fuse together you know but they might like when you extrude them as you 3d print they may touch but you can easily just pull those apart and now I can actually sort of bend this open and then bring it around the container and snap it into place so okay these are the strategies I used to create these I know I kind of threw a lot at you here but some very valuable techniques that can be applied to 3d printing finally let's just bring in the appearance option here and I created some favorite appearances so I'm just going to drag the sky blue to the container the white to the pattern and I have this wood material this ash to the lid and you can see here I've got my lid got my container and then I have that key pattern here that will be in lay that will slap snap snap right into place so that's that's the approach and then I'll show one more thing really quick and that's printing let's go back to that key pattern and go to an isolate and that's going to bring in all those support structures so if you want to print all these together what you would do is oops come up here on your browser let's drag this if you don't see the top drag this up I've got a bunch of bodies so you get a little scroll bar here the top where it says the name of it right click and go to save as a mesh and I'm going to send this straight to my 3d printer so you can see my application here is my Prusa slicer I'll click ok and doing it that way whatever you have toggled on it'll actually bring those right into your printer and since I want all these bodies you can see they come right here all together the only thing addition that I did here to make this print well as I added a brim so if I slice that you'll see there's a brim around here so that this will actually stick on the build plate because this is such a thin profile here surface area that it has but that's that those are the techniques that I used to create this model here and create my own support structures to print that key pattern and had a really really great model and a fun project that I enjoyed doing one thing I did actually let me see did I do that yet is out of fill it here to the bottom there so let's just do that really quick modify fill it select that bottom edge maybe do like a five millimeter fill it and there you have it I'll just make that bottom a little bit stronger all right I hope you enjoyed this video if you did and you learned something let me know in the comments what you learned and if you have any questions on any of the steps I took leave that in the comments as well I've got a bunch of resources down below if you're looking to learn
