 Here's this week's project. Yeah, it's a container. But come on, how beautiful is this container? The lid is printed with Matterhackers wood PLA, and the bottom is printed with this beautiful matte sky blue PLA from Overture. The white inlay Greek pattern is white PLA, but I don't know what brand this one is. It's just some generic PLA I had lying around. The technique I wanted to explore with this project was printing a circular inlay pattern that wraps fully around the cylinder and simply snaps into place. I want to devote the next few videos to this design because although it may look like a simple container, there are quite a few interesting design techniques I want to show. Now for my Patreon supporters, I've gone ahead and uploaded the full 40-minute step-by-step tutorial along with the Fusion 360 file.

Also, if you'd like a more structured approach to learning Fusion 360, check out my Fusion 360 Quick Start course, link below. Okay, back to the beautiful container. I'm going to separate this project into two videos. In this one, I'll go over creating the circular inlay and how to create a perfect wrap around the cylindrical object. In video two, I'll discuss my technique for isolating the pattern and preparing it for 3D printing. The techniques I used to design my own supports in Fusion 360 that allowed me to go from this to this. I didn't begin this project with the inlay approach in mind. Like most of my projects, it kind of evolved into that. I first intended to print everything as one piece and simply paint it. Because I had added chamfers to the wrap around pattern, it made it hard to paint in the lines. Also, the fact that I'm not a great painter and can be a little impatient compounded the problem. I decided I would just over paint and then come back and clean up the paint later. Well, this didn't work exactly as planned and we won't talk about this anymore. So I decided instead of printing the container in key pattern as one piece, I would print the key pattern separately and simply glue it into place. Something like this. And then I decided I would add a chamfer to the bottom that would align and hold the key pattern at its proper height and inlay the top ring. Then I thought, well, why not just make the key pattern as an inlay? This introduced new issues I would have to solve such as printing this circular pattern with one extruder without having to deal with the nightmare of removing and cleaning up a mess of supports. I'll save that part for my next video. And in this video, I want to show how I approach the wrap around Greek key pattern. All right, let's begin with my approach to designing this Greek key pattern. First, I'll begin by explaining a quick concept and then we'll jump into the design. So here I've got a cylinder and in front of that cylinder, I've created a sketch and on that sketch, I've created this rectangle. Now, if I open up that sketch, you'll see that I've constrained it in certain ways, but I haven't fully constrained it. So I've given it a height from the bottom here. I've given it a height of the rectangle, but I didn't constrain the length. And you can see that that's 140 millimeters. All right, so because I didn't constrain it, you see that it's blue instead of black here. And I also can just click this and drag it to make it wider. I'm going to leave that open for a reason or I should say unconstrained for a reason. So I'll finish this sketch. And I can now go ahead and let's create an emboss. We're going to emboss this rectangle onto that cylinder by going to create down to emboss. We'll select our rectangle here and then for our face, we'll select our cylinder. And it takes that sketch here, that rectangle and creates an emboss on the cylinder. And we know that's a perfect emboss, because if I click here, again, that's 140 millimeters. And if I click on the inside of this edge here, actually it gives it to me in radius form. But if I go to inspect and then click on it, it now gives me what that length is, 140 millimeters. So that tells me that that's the exact length of this rectangle. So we have a perfect emboss there. Now I can go ahead and take this rectangle and just drag it out and notice how the length of that emboss will grow. It's going to continue to match whatever the length of my rectangle is here. And that will continue happening until I exceed the length of the circle, that circumference. So again, if you select it, you'll get it in diameter form here. But if I go to inspect and then select it, you'll get that circumference here as length. So the diameter was 100 millimeter, which makes our length 314.159 millimeters. And currently our rectangle is at 269. So I can continue like slowly tweaking it to try to get it as close as I can to meet. And the issue here is if I go over, like if I take this and I drag it way out, it no longer refreshes. In fact, it'll give me like a quick warning here because this now exceeds 314 and it can't overlap itself. And the way to bring it back is I have to bring it back again below 314. And then, so that's still too high, bring it low, and then it'll continue to be dynamic and respond to the emboss. And so, you know, I can try to like really try to nudge this in to get it as close as I can. If I go over, bring it back. But that's really a silly way to approach this. We can simply go ahead and define this to equal the circumference of our circle here. And that should get it to give us a perfect wrap. So what I can do is go back to that sketch and say, all right, let me just add a dimension here. Just put it up here and do 314.159. Enter. Now, if I click finish sketch, that's going to give me that perfect emboss. Okay, wanted to establish that and now we'll jump in and create our Greek pattern key to revolve around our cylinder. All right, I'll begin this design by first, let's create our cylinder and I'll go through this really quick because a lot of this is quite straightforward. So I just created a sketch on my XY plane. I'm going to start with a cylinder here right on the origin. I'm going to start by giving it again a radius of sorry, a diameter of 100 millimeters. And then I'll finish that sketch. Let me extrude this up, go up 110 millimeters. Let's create that offset plane here. I'm just going to grab that sensor plane, drag it out. Let's go, let's say negative 70 millimeters sounds good just to put me right in front of it. Then I'll create a sketch right on that plane I just created and we're going to zoom in. All right, now I'm going to project the outline of my cylinder by hitting P and I'll simply click the specified entities, click on it, click OK. Now I can remove my or untaggle the visibility of my bodies here and I'll get that top and bottom line showing me the edge of my cylinder. All right, here's the approach I'm going to take to create the Greek pattern. So it's important here actually which makes it a lot easier to follow this is if you just use your grid spacing here to your advantage. So you want to make sure it matches mine. So if you go here to your grid settings, click here on grid settings and then as far as the two options here you have adaptive and fixed check fixed and then go ahead and change your major grid spacing to 10 minus subdivision to one and click OK. All right, now each of these blocks here, the grid is 10 millimeters and so the way I approach this is I went up, I'm going to go up six blocks here to start my sketch. So one, two, three, four, five, six right here. I just determined that starting it there is going to center it right in the middle between the top and bottom lines and that way we don't have to worry about moving it into place later. All right, so I'll grab my line tool here from the create menu or simply hit L and I lost my place two, three, four, five, six. I'm going to start here. I'm going to go down one. So just a way you can make this pattern is you increase the number of grid spacings by one each time. So down one, right two, up three, left four and then down five and then we're going to go to the right another five and then so that will end at just one grid spacing from this edge here. Click that check mark and then we're going to do the same thing on the inside right here. So one, two, three, four and then four there and then we're going to close the ends here and also this one here and then we have our key pattern. Okay, so the approach I took here if I see if I click on this line here we can see that that's 50 millimeters right. Let me finish this sketch for a second bringing the body back into view. Now this length here or our circumference is 314 right. So if we want to get this to wrap around the circumference here right like the total length here has to equal this circumference here. So you know one way we could do that is if I go back to the sketch we can create a rectangular pattern of this and get it to equal 314. So let's say we'll just do that for a second and then I'll come back and show a different way. So let me create a pattern here. So a rectangular pattern. I'm going to double click to select this chain my direction. I'll click this bottom edge here to set the direction and I can start dragging this arrow across actually. I know that that's the length there is 50 millimeters so I can change the distance type to spacing go ahead and type 50 for distance and I know since this is 50 millimeters long if I make six of these it's going to get me close right it'll get me to 300 millimeters. Change spacing or distance here back to 50 instead of 80. Okay now I have that I can finish that sketch and this will be I can do a quick inspect here to verify between this edge and this edge 300 millimeters. So I know that this is 314 the circumference so it's not going to give me a full wrap right so I can go to create I can go to emboss select each one of these and then select my face and then I'll have this and so we can see it's looking looking good but then we've got that spacing there right because we're about roughly 14 millimeters shy. So you know a few options we can go there we can come here and make sure to change this so that the full length equals exactly that circumference in this case it's going to be easier to change that circumference to match the 300 here. So let's do that instead finish sketch go back to that first sketch where I have my circumference there. All right here we're gonna have to go back to some old algebra days right so the circle wants to be defined in terms of a diameter and we know that the circumference of a circle equals diameter times pi so we can solve for diameter because we know that diameter equals circumference divided by pi so in that case if we know we want the circumference to be 300 millimeters we'll just go ahead and type that formula in so that would be 300 divided by pi and you have to be actually I'll show you you can type 3.14 if you want but you know if you want to be more precise just go ahead and type pi and that'll give you a lot more significant figures there so to type pi you're gonna have to do capital P and I small p and small i will not work here so you'll need to make sure that that you have capital P and capital I will enter and now we'll get our diameter that we need to give us that circumference which is 95.493 click finish sketch and we can see here that well our circumference definitely changed but it didn't update our emboss here and this is there's actually an issue here and it's a rounding issue is what it turns out to be so because we entered pi there and if I go back to this sketch here you know this distance here is 300 which should equal exactly the 300 of the circumference there but I'll show you why I think it's a rounding issue if I click finish sketch I go back to that first sketch here where I define this if I go back to the dimension here basically what it comes down to is that this circumference has to be exactly the same size or a slightly bigger than the length of my emboss otherwise this will not work so what I'm gonna do here is go ahead and add 0.001 and watch how that fixes it if I click finish sketch here perfect no more error and I get a perfect emboss okay now that I've shown you that I'm gonna show you another way which I think is probably a better way to approach this notice also you have that little seam there it's not really gonna it's not much of an issue actually it won't even show when you're 3d printed but notice this next approach I'm gonna show actually you won't even see that scene so alright I'm gonna undo until before I created this pattern here of the sketch so I'm just gonna keep hitting undo until I go back to one pattern here okay a better approach I found to do this is to go ahead and just emboss one instance here so if I go to create down to emboss select this and emboss it onto my surface here I've got one and now if I create a revolve of this it'll actually work better so let me first go ahead and come back to this first sketch I ended up undoing that part so I have to redefine this 300 divided by pi gives me the right circumference I need and now I can go to create down to pattern do a circular pattern type I'm gonna do features select my emboss and then the axis of rotation I can go ahead and select the bottom edge of that circle there and I will enter six of these for my quantity and enter and now you can see how it worked perfectly and I didn't have to worry about the whole rounding issue here by adding you know point zero zero one to that circumference so that ended up working a lot better and I don't even get a scene in here so it just does a perfect emboss there okay and you can see you know definitely if you wanted to approach this with user parameters you can put all your formulas here and make it so that this entire thing is fully parametric you can even go the full route and make for example this sketch here so that this pattern can fully change with the circumference of your cylinder a little more involved you could definitely do that okay I'll end it here because I don't want to have this video go too long but basically I just wanted to show the approach I took here to create that perfect emboss around a cylinder and in the next video I'll talk about how I then got to this part here which I got that pattern to be an inlay inside the model here and some techniques I approached here to get this to print so you can see I've added some chamfers here to the cylinder which allows this part here to actually print without supports so I want to talk a little bit about that technique in my next video and also talk about printing this shape here because you can see this would be a nightmare to print if you're just using one extruder for example I mean if you've got like the multi material unit where you can or multiple heads on your printer where you can print your supports in a different material or you can print two colors at once you know you can get away with printing that but a lot of us just have a single printer with one extruder so we have to kind of get creative and how we model our designs and so I really wanted to approach this with a way that you know didn't have to generate supports within the slicer so that they're easily removed and I want to show the technique I took there to print this and get it to fit exactly on this cylinder and of course I have the lid here which also got to fit perfectly on the container but I'll save those for next video here just wanted to keep this straightforward to one topic and again I have the entire I think it turned out to be like a full 40 minute tutorial on my patreon page so my patreon subscribers you have access to that plus the Fusion 360 file for this design here also can you guys see how I'm sure I'm gonna get this question but you can see there's a little gap sorry this trying to get in this line a little gap there between you know the inlay and the container for my in order for this to fit but I'll talk about that in the next video okay yeah so patreon subscribers you already have access to the full tutorial on my page and if you're not yet
