 Okay, the final video in my rack and pinion series here will be printing out all the parts here and then assembling them and seeing if everything works out perfectly, if our clearances are correct and we can actually get this to perform as it does here with our joints. So we're going to go ahead and send this to our printers and I'll show you in this video how I'm going to lay out each part and how I'm going to slice it. And as you can see here, I went ahead and modified the colors just to give it the colors I'm actually going to be using when I print this or the filament I'll be using. Alright, let's begin. First thing I'll do is I'm going to send the base to the bamboo. In order to do that, I'm going to untaggle the visibility of the spur gear and the rack. And if you recall, the base is made up of two bodies. I've got the actual base part and the pin. Okay, we're going to right click up here on the top of our browser and we're going to go to save as mesh. And over here, my dialog box, I've got sent to 3D print utility and I have my bamboo slicer as my slicer of choice that this will default to. I'll click OK. Alright, and this is brought into the bamboo slicer. Let me open that up. And a few things I'll show you here. This is brought in, it comes in together as one unit, even though there's two separate bodies there. What I'm going to do is click up here to split to objects. And then I'm going to go over here where it says process, I'm going to go from global to objects. And you can see here I have my both parts here. I'll click on a black area here to deselect them both. And now I can click here and just drag these out. And I've got two separate bodies here that I can move individually. Alright, so next part is figuring out what's the best print orientation for this. Now bamboo studio does have a very good auto-orient option here. So if I click on the base here and click on auto, it'll actually orient it to what it believes is the best orientation to 3D print this. And this, I think I will go with that orientation, actually it's what I was thinking. The other option would be to print it in this orientation here. Which is fine, but it would take longer and you've got less of a surface area. You know, ideally I would love to print this on this surface here because that would give me the perfect hole. But that's not going to work because it would require supports on the underside and also supports over here. So I'm going to have to make a compromise here and the best orientation is going to be in this orientation here. Alright, and in the pin that's fine the way that's orientated, that's exactly how I want it. Alright, I can click on auto-arrange to have it arrange everything as the way I like it. Let me show you something here actually and I kind of have the setting already done but let's go back, I'll undo it and then show you it. I'm going to go back to global here and within others, well default it's by layer so let me just go back to that and go ahead and arrange this again. So if I slice this and I print it by layer, what it does is if I bring down a simulation here, right, it's going to print one layer of each going back and forth until it finishes the pin and it will finish printing the rest of the base. But I often like to take advantage of the print by object. So within the others tab you go down to special mode and you can change the print sequence to be by object instead of by layer and when you do that if you haven't arranged your part correctly it's going to give you an error that says they're too close together and that would be a problem because it would knock one over while printing the other because it completes one and then goes to the other. So what we can do is we'll go back to prepare and you can see here that you get these outlines around the part telling you how far apart they need to be in order for this to work. You can also use the auto-arrange tool here and it'll automatically arrange them where it believes works. All you have to really worry about is that when you do move these around that these circles here don't overlap. In this case, interesting, it does the auto-arrange and it's overlapping them but let's see what happens if I slice the plate. It allows you to slice it which is interesting. I would have thought honestly I would have needed something like this for that to work. So it's interesting that it allows it to go here even though the circles overlap. I don't know if that's a bug or not. I don't feel like testing that right now so I'm just going to do this and I'll come back and maybe do a separate video where I test this. But here I know clearly these circles will not overlap and it'll be fine. So now when I slice this I can take the slider up and down and you can see it's going to do the pin first and once it completes that it's going to go and do the base over there. So this looks good. I'm happy with that. I'm just going to go with default settings. I'm going at 0.2 millimeter layer height resolution. This is going to be white so let's go back to prepare and I'm just going to select on the object and click number two here for both of them. I'm just typing number two because that's the... Oh okay it's got it as ABS. That's not what I have on my filament AMS unit and so I'm going to click on this sync button here and it's going to go ahead and click resync and it'll sync to the actual filaments that I have here on my printer. So that in fact is bamboo PLA mat. All right now that that's all set I'm going to go ahead and slice plate. You can see here this is going to be total 58 minutes and print and send and there we go successfully sent and we'll check on that in a minute. Okay now that I have the bamboo printing I'm going to bring back the other models I want to send so this time I can untangle the base and I'll go ahead and send the spur gear next and I'll send this to the Prusa mark four. So let me untangle the rack right click save as mesh and this time I'm going to change it from bamboo here to Prusa slicer so I'm going to click on that little folder select from my computer and I created a folder here called slicers that just allows me to go back and forth between the two really quick so here I'm going to click my Prusa slicer click open and you'll see this update to Prusa slicer and then I'll click okay. I really do wish Fusion would include at least two other options here or just total of two options at least for slicer so I can just go back and forth but you know this this works. All right I'll click okay and this will fire up my Prusa slicer and throw my gear here and here I'm going to change this from my mini to my mark four. You can hear my bamboo in the background firing up. All right I'm gonna just go ahead and center that I'm gonna go with the default 0.2 millimeter layer height here and click slice. All right let's take a look at that simulation. Everything looks good we're looking at 28 minutes and I'm gonna export the gcode. All right I'm gonna go ahead and delete this go back to Fusion and bring back the rack so I'll untangle spur gear toggle rack right click save as mesh click okay it goes to my Prusa slicer now this is going to my mini so I'm gonna go ahead and change the printer over here for my mark four to my mini and it's select my object here I'm gonna click place on face click on that bottom surface to reorient it click the part and click center or arrange object outside okay we'll move it in and then click arrange. That's weird I wonder why is this arrange not working. Arrange ignored the following objects which can't fit. I don't know why it's telling me I can't fit I've never had an issue with this before actually but it looks like it fits fine I don't see anything else I'm here you could hear my bamboo. One thing I gotta say is the Prusa printers are much quieter than the bamboo but I love all my printers. All right back to this guy I don't know arrange ignored the following objects which can't fit into a single bed that error is not making any sense to me like I said I don't ever recall ever getting that but we're just gonna manually place it on the center slice it slice fine if anyone knows what the issue is with the error let me know all right simulation here looks pretty good to me I'm gonna send it as is not gonna fuss too much about it export now I've got all my files ready to print okay I'm about 25 minutes into the print here on the bamboo 32 minutes left and let's take a look what's going on here so I can see okay I was so loud in the printer that it was just too hard to hear me so I'm gonna come in with a voice over here basically you see the two parts so it finished the pin and it moved down to the base but the one thing that has me concerned here is if you look on the left portion here it's starting to split from the bed a little bit you can see it rising up in here the slicer actually recommended that I use brim for this part and I chose to override it thought it would be fine and I'm regretting that decision right now so I end up just cancelling this print and then resending with the part by itself with a brim enabled since I went with the print sequential option I don't end up losing the pin since it's already finished printing that part I've got the rack printing and the mini in the first layer is looking excellent and moving on to the mark four I've got the spur gear and here I'm running the mark four with input shaping enabled so you can see here how that looks all right got my parts here ready to build so let's go ahead and take off the rack here nice little flip there okay so this looks pretty good here set that aside and I already removed the spur gear in the pin here I have the base here and you can see let me take this off first you can see here um the concern I had with the hole um it's fine up until you get to like the right tip pretty top there and so we'll clean that up a bit the brim here comes off nicely and for that hole I'm actually going to use a deferring tool here and maybe just go over it and just to clean that up a bit it's a really great tool to have it be right here as well all right so the pin should fit there nicely okay yeah it's a nice fit not coming off okay so that works well let's try the rack I want this to be able to slide in and out there it slides nicely so I think we're ready to go all right let's go ahead and let's say I think I want to put the gear first and then I'll put the pin in should be able to just oh this is a little tight here oh ah crap back to the drum boy um did I forget to do an offset between the gear and the pin there um looks like I don't have a clearance should have tested that first not that's really in there all right I'm gonna have to get this out and it looks like I'm gonna have to reprint the pin with a clearance there it's gonna be faster to print the pin than the gear so uh all right thought I could do this in one shot okay back to fusion here just wanted to check if I indeed forgot to put that clearance in so let's take a look if I click here on the edge of the pin here I get the diameter showing that's 12.7 and if I click on the edge of the gear I can see that that's 12.7 so there lies my problem all right so here what I'll do is I'll go back to that in component here which is within the base component so let me toggle that on and toggle the visibility of the others I'm gonna bring just the pin into view here and what I need to do here is go to modify press pull I'm gonna take this and let's go ahead and give this an offset of let's say negative 0.3 millimeters and click okay all right and I'm just gonna resend this and we'll try it again all right printed a new pin here you can see the old one here I broke that off got two pieces and all right so let's try this now before I put it in let me see if it actually fits in the gear here and that's a much better fit so that's a 0.3 millimeter clearance there okay so now I should be able to put the gear align it with the base and snap this in and this moves nice and I should be able to put the rack in and if I just go ahead and let's see look at that okay so you can see it a little better that works nicely just like fusions that it would all right well there's always that one I feel like that one clearance that you forget to set so it's it's it's rare that you can get it all in the first try but overall I'm gonna call this project the success one of the things I want to point out before I wrap this up is just the clearances here between the parts and the differences in each one so let me just pull this apart really quick let's take a look at that so with the pin I use the 0.1 millimeter clearance right and you can see that snaps in and I could move that that's not coming out it gives me a good friction fit you know now there are a little bit of you know it's not perfect because of the the way the circle here was printed or that hole being vertically versus line horizontal so horizontal would give you a more accurate representation of that clearance but it still works out like this is still the job is done I put that and that's not coming out now with the rack here I went with a 0.2 millimeter clearance and this is like I brought this wall back and this wall here back these two walls here back a 0.2 millimeters right so total it ends up being a 0.4 millimeter clearance and you can see how that slides back and forth really nicely and then the last clearance I used was between the hole and the pin here and this I used a 0.3 millimeter clearance now it's a little bit difference comparing you know circles to sort of rectangles where you have to extrude two walls but again you can see how that 0.3 millimeter clearance fits and how it not you know if I had used a 0.1 on this I wouldn't have gotten this nice spin here so it this comes with a bit of just you know testing for your printer and just experience where you would kind of say okay I think this is going to need 0.1 versus 0.2 or 0.3 but in the end I didn't really plan it that way but we got sort of a nice representation of you know 0.1, 0.2, 0.3 millimeter clearances here so okay I just wanted to point that out all right that wraps it up for this project hope you enjoyed this if you've
