Fusion 360 — How To Model Snap Rings for 3D Printing — Ask LarsLive

next one here is from JT hey JT uh-oh this is a good one for anybody doing 3d printing it's a 3d printer one that I think is really good alright this is from JT he says I have been scratching videos now that he found a video by a guy named Adam James and you should definitely go and check out Adam James so let me just go back here let's open up a new file and Adam James so that is his is YouTube channel and I'm James maybe shirts that fit in fusion 360 hit the subscribe button people love this I don't know why he got three that it's not deserved James if you're watching this absolutely superb superb but talking about making kind of a snap fit on this model for freedom printing so again you should go and check out this YouTube channel check out this video great job Adam if you're watching these videos man that is an awesome love to see more stuff from you but the one that JT is talking about that is different from this is doing this on a cylinder because the way that Adam does it is probably the way I would do it too is projecting some edges and just using the extrude function but since you now are going from a square box to a round cylinder JT I don't blame you for struggling let's go ahead and do some let's go ahead and do some free D printing here so let's make a canister first so I'm gonna go in every to make this a multi body kind of part so I'm gonna right click here and and do a and this would actually also answer I think Justin's question so I'm gonna create a new component and in this one here I am going to open up a sketch it's gonna be a cylinder so let's make something that is 100 millimeters in diameter let's extrude this up so we're gonna make this fancy cylinder in here let's make it 200 millimeters tall and I'm gonna use the shell command so make this a silver here ten millimeters and in Sedona like this now this is this is gonna be a cylinder that we're gonna be using meet up add some fill that's later on but this is the first time now we're gonna create a lid for this and there's gonna be this snap fit lid in here so I'm gonna create a new component hopefully this will just rename this call this face let's right-click and say new component and make this lid okay and we're gonna open up a new sketch and let's do this lid up here now I'm gonna hit P for projects and I'm gonna borrow that that X therefore for my lid now in Adams video Adams talking about he likes a tolerance about a half a millimeter on on his 3d printer so I'm makes it gonna emulate that in here so I'm gonna hit all four offset and I am going to add in a half a millimeter in here this really depends on what your what your printer is into and I am actually gonna do another offset for the outside of the lids again and you can't offset the an offset offsets are not the circuit inside that's here 0:04 offset and I'm gonna do the outside of the lid this is that a ten millimeter lip right there now just to make sure there's no confusion I am going to hit cue for press pool and I'm gonna make sure that I select that outer edge there and I'm gonna make our tab down here now I don't know how long we're gonna make this cover that goes over here but I'm gonna make it twenty millimeters like that's and then I'm still doing the component lid I'm actually gonna do and now they're extrude and I'm gonna select that inside platform we had in here should like to be able to select the whole thing let's open a new sketch select here and let's hit P for projects so like that one can definitely do that's it Q and then I'm just gonna give this some thickness here and these will merge together if I have joined let's just make okay so that all became became one so what do we have now this was a lot of stuff we have a base here right so that's the base we had to live going over here and then we have and put it together we kind of had this lip now we should have a gap in there if you go in and say inspect some government of freedom mouths it's moving and let's do it see how the thought is rolling on the screen that's annoying section analysis and missus turn the organ on and let's do a section on here and I should definitely see a gap in here okay good there is again alright now drives me not nuts we can turn the analysis off now we actually gonna do the I'm gonna do the calling and again the step fit and I'm gonna do that on the base first I'm gonna activate the base then I am gonna open a sketch on the side you here we're gonna use them involve again remember that what we're trying to do here is actually a a snap ring so we can't project we're gonna do the Raval so I'm gonna p4 project and I'm just gonna select not gonna select that top component I'm gonna title it oh it's like that and let's dry draw up our snap fitting so I'm gonna go ahead here on the sign here and I'm just gonna draw up something that's gonna be my snap fitting right there and close that off and let's make sure that this here is this and in and then we could do a to that deeper dimension now again Adam did this as a 45 degree for his and we probably just have to make sure that we don't make this too long so let's just make this 10 this is this good I think this is good let's turn the lid back on and kind of see the lid sitting there maybe we actually wanted to be kind of like a little bit more Center so you could just play with this dimension here let's make it 15 ways to live now that's good enough that's good enough for us so now I am gonna go into the revolve and we're gonna select this profile here and it's gonna be over the center of dimension that's so now we have this this lid here right turn the top lid on and actually you could do something cool here if you haven't done this before we could go into inspect and you could do an interference and if you select the two components like this and click the little compute yep it acts sees here that actually finds that that interference now here's what I would do that I think that some people is gonna find interesting is I would use the combined tool I would set this to John at two cuts my target body is gonna be the lid right I definitely have a issue with the graphic representation and the that's gonna make this a little harder the tool body is gonna be this okay and I'm gonna say key tools hit ok now what I got if I just turn the base off is you will see that I actually have that ring in there and if we turn this section analysis back on you will also see that we have that ring in there but you will see in here that we have the clearance but we don't have the clearance on the lid on the step fit yet so that is a little bit of a problem so let's go in and fix that I'm gonna turn my section analysis off again makes it just gonna go into the lid right and if you go in here we can exit just select the face and if we hit Q we can actually stop them adding or offsetting these faces so I'm gonna go - point five on one face go up to the other 45 there he Q and I'm gonna go - point five and just like that I have offset those two phases out or fine so we go back into our base again and let's go in and turn the the section analysis back on you will now see that we have that have millimeter of 1/2 millimeter of them of clearance so the last thing we would do in this model is let's get out of the section analysis is let's add some XE you can either add some champers or some fillers I would probably add some chambers to this part so let's try a one millimeter chamfer - that would probably be good right there just to make that look nice and let's do that to the other end too just because that makes sense that's driving me nuts with these with this mouse I can't work without of them ok and then I would get some Phillips to this so probably had a small little filler here that's 5.5 that's kind of like our clearance remember that one um and then I want to add another filter to this one here you can make that one that was a little bit - OH - one okay and then let's go back into the lid and let's do the same thing to this now I would definitely make sure that I added a chamfer on this one and this one should definitely minimum be one I might even consider how does it look at - yes that could that would help that thing going on there and then we can go back in so I'll fill it and this one here we make that one one also and this is more actually you know the only reason I will probably add a fill it in here would probably do um to do a little bit of of them to do a little bit of clearance but actually you know what I might only to do some strength but I might actually make that one a little bit less because I know that this is where the printer is going to struggle the most with for that with that clearance if we do that and we turn this back on here I should actually also and just go back to the lid here let's add a chamfer on here and here and make that one and in here we should absolutely also add a little bit of strength that's why we're putting the fill that's in this just for strength now we've done all that let's turn the bass back on and let's go in here and do the analysis this is your best friend at this point so just go in and take a look and just see how we have all these different clearances in here so that looks good and of course turned analysis back on you could go back in and use that interference tool to highlight these two don't if you have included coincidence you will see an interference on where they're touching on top here you will see no interferences and this would be a perfect good model for the snap thing now I would maybe consider doing another thing guys and that would be with you look at turning the lid off this might this may be something to play around with this snap fit really has a lot of area to snap over right the more area you have because it's round you might consider to be a little bit creative and what I mean by that is just to be a little bit Vance you might go in here on the bottom and decide to cut away some of these so what I maybe would consider doing is to do something like this here I think I would probably go in here and create something that I would do this that's I would create something but I mentioned 60 let's create a this for the mention and let's make this 60 degrees and this also dimension also make that 60 let's create a now I am modeling on my feet here that there people put jacks and let's go in and make sure we we get one of these that just the lid on so this your thing let's do a cuts let's cut this through here right so we kind of cutting that and if we go in and we do wow it's annoying that that part is moving on me I might have to abandon this and let's go in here let's do a feature I'm gonna select that feature select an axis to me that's the axis there and if we did three of these then you would end up getting three of these this might help you cutting this down and you maybe have seen something like this done before now you could now I also add you would go in here and add some more I would probably prefer the chamfer on here versus the Phillip but if you're go ahead and do this fill it here point five edges on this I'm sorry that my 3d connection mouse is moving on me what makes it a little hard there we go that I think should be a super good snap fit for this what I'm actually gonna do here and this was for dat I makes it gonna save this file I'm gonna call this one JT so we make sure we have that one and now my pop stopped moving and then I'm just gonna quickly answer Justin's question is when you have multiple files here if I wanted to get this into a 3d printer like this how would I get multiple parts like we have in here into into the 3d printer and the best way to do that is right-click say save s STL okay and that's gonna open up this dialog you can say save it out at individual files and then I'm just gonna select the whole thing here you can excel so select over here I believe select them all and I'm gonna select them like this it's save let's leave this to st ljt version one all the phoebe prints like this save it's gonna work like this and now if you open up our downloads folder you will see that we have these files here and heck while we add it let's open up the cura because people it's gonna ask me about this that's like five questions and we already had an hour this is going a typical hangout I should have opened up sure up first sorry about that sir that sure is firing up that is the the Cure here so now we can go and say Open File open up one of them that was a little big on my my 3d printer huh and let's go ahead and open up the second one so that comes in there and now I am NOT a cure a master but should we get these two in on the folder there now I would think you tell me wrong um probably want to do it probably want to flip this one around right now this now I free deep into people it's gonna be it's gonna be yelling at me right now okay so that is good if I just spin this around I'm within my build envelope I can see that do I need support material uh to to print this up I actually don't think I do so we set the in filter to you I'm gonna turn off supporting see support is not in the air believe this is a layer height of maybe one let's hit slice this is when I am in my nut in my comfort zone with 3d printing but hopefully if somebody's looking at this right now and find this one super super useful so we're gonna slice this and a little bit afraid about how long does it's gonna take to do but you know what I'm gonna run this I'm gonna run this and hope that the 45 degrees let's take two days to do this do I really want support material to do that 45 dries does that is that needed there's the problem I think I have and I could probably somebody correct me but if I turned it the extrude a chew on and slice this I think this is gonna take a lot longer to do because then it's gonna go in I really want to do this size though it's gonna go in and do this and I think it's gonna put support material anywhere and I don't know how to fix that because I haven't played enough with the cure settings but I might just also just bite the Apple and do it all in with the support material and then have to to deal with the fact that it's gonna take eight days to do this though they are leaving for the fusion attempt she's gonna take an extra day to do the support material feed you here it's gonna means they put support material everywhere right inside that cavity what do you guys think see do I really need support material to do this to do that forty five guys is that needed somebody's commenting right now so the right thing to do would probably to not print both of them right now and just print the lid and find out if I need the support material or not that is probably what I would do I would bite the Apple bite the Apple that would just say in here and say prepare this model here let's move that and if you're just trying this without the support because if we can do it without the support material on this one this is only gonna take 13 hours then then I know I could all just scale this down right you could also chuck one of these in half I'm gonna go ahead and bite the bullet on this and say let's just print this over the network without it without support material and I'll learn my lesson and I don't waste all the all the different all the different materials what's this useful it's ready it's getting ready okay maybe there's got a little bit too long I'm sorry dude see if it did I hope I showed some really cool things we'll see how this come on I will print this one but I makes it not gonna be able to show you the second one because I'm I'm traveling this it's gonna take few days I'm leaving - all right we're gonna hit this we're gonna end this segment right here if you like ah this thumbs up if you don't that's okay thumbs down we all in an hour but I'm gonna have to take a couple of mold here so subscribe if you haven't subscribe I would truly appreciated subscribe to the channel [Music]
