My Plinko Puck // Fusion 360 and 3D Printing

[Music] [Music] hey pretty cool huh no it's not another fidget spinner don't worry but what is it well I'm going to the matter hackers meet up on May 3rd next week and I heard they're making a giant Plinko board so I suggested it would be super cool if everyone could make their own make your coin Plinko pucks and give it a shot on the Plinko and try to win some prizes they thought it was a cool idea so I whipped this thing up as fast as I could sure it's nice to keep things simple sometimes but with this particular project I wanted to play around and see how many cool little features I could fit in so of course you can see the logo stays upright which is super cool and then this swirly pattern is actually a built-in flat spring so the puck will bounce a little bit more and hopefully make a better show when it's running down the Plinko board and I also use flexible filament on the edges here to help with the bounciness and shock absorption in order for this to work all the pucks have to be the same size so that they'll all work on the same Plinko board so those are the constraints they have to be three and a half inches in diameter half an inch thick and the edge features can't be more than an eighth of an inch so within those constraints I wanted to see how crazy I could get and this is what I came up with I really like how it turned out so I'm gonna show you guys exactly how I made it right now let's go of course we want to start by creating a model of what we're gonna print so here I am in fusion 360 and the first thing I'm gonna do is draw out a half profile of my puck that way I can revolve it to create the full disk and get all those important dimensions in there since I'm revolving around the right side of my drawing that rectangle on the Left will become the elastic ring that goes around this whole disk for the I'll give this whole sketch a dimension of 1.75 inches that way when it's revolved all the way around the width will double to become the 3.5 inch diameter that we want this puck to be I'll also include the height and make sure that all these details on the edge don't go beyond an eighth of an inch from the rim once we revolve that we've got our nice puck shape with all the correct dimensions and now we can just start adding on the little details and features that I want to add so let's start with those flat Springs I sketched two circles one near the center for the start of the spring and then one on the outside to make sure it ends before it gets to the very edge so that we have a nice thick rim as well then I'll do a tangent arc from the inner circle to the outer circle halfway around and I'll offset that to give it the thickness I want and continue that arc the other way around so that it meets up with that circle again now I want to create a pattern of several of these arcs going all the way around to make things a little bit stronger and just so it'll look cool so I don't want to cut it away but instead I'm gonna make a new body with just that arc and I'll extrude it to be the same height as the rest of my disc I'll make sure to save that as a new body and then I'll hide the puck for a minute and pattern this arc all the way around until it looks the way I want it to we'll go with five instances I think that looks really cool and then I can use the combine feature to combine these all into one solid body I'll also put some fill it's here in the sharp edges to make sure that there's no high stress points that might break apart anytime you have a sharp intersection like this affiliate is a good idea to relieve some of the stress that could concentrate in that point okay so now to combine these arms with the rest of the body I'm gonna go ahead and trace out that inner and outer circle again and I'm gonna use those circles as a split tool to cut my puck into three separate pieces once I've done that I can select the mil ring and do an intersect command with that and the spring arms that I created and when I combine that all back together again I'm left with the shape I want and this creates some more sharp points here on the outer so we'll go ahead and apply the same one millimeter fill it on all of those as well next I want to add my emblem in the center but before I do that I have to extrude inwards because I can't have any features sticking out or making the puck any wider than that half-inch constraint anywhere along this design so instead I'm going to dip it in words and then have the logo embedded inside of my puck so I did that little tapered extrude and then I'll extrude a new disc inside of there which will be the separate logo part alright it's really coming together now I have a good idea of how it's gonna look let's apply some different appearances so that we can just make it look a little flashier and get excited about what we're making and then it's time to flip over to the back and start working on the mechanism to keep my logo spinning and upright so to do that a hollow out the back make a hole for the bearing to fit into place and also design an axle to go through that bearing and hold on to this weight section on the back basically I'm creating an off centered weight here so that it's always drawn to the same orientation because of gravity and that's going to be connected to the logo so that the logo is always facing the same way as well I'm also going to separate the different parts that way I can print them with different materials and also so I don't have to use so much support material for all these different parts I did finesse things a little more but we're pretty much done here so let's go ahead and take a look at the printed parts here's the main body printing out on my CR 10 in this lovely pro PLA from madder hackers this is one of my favorite blues and this piece actually did require some support material so I'm gonna go ahead and pry that all out and reveal that hollow section in the back which is going to hold the weight here you can see that springiness that I built into the part I printed the logo using a color swap and a point two millimeter nozzle so those triangles are nice and sharp and everything looks really clean and then for the weight I actually printed that using a protocol stack opera fill which makes it really nice and heavy and this came out looking really beautiful printed with the point six millimeter Olsson ruby nozzle I printed the flexible part with some Isan TPU I had laying around and while it's not super stretchy it is flexible so hopefully that'll work out finally there's this little axle that will connect the weight to the logo and then we have all our 3d printed parts add one ceramic bearing and we've got all the parts we need so let's start putting this together first we're gonna take the body and fit this elastic band around the rim like I said this flexible filament wasn't super flexible but it was just enough to snap it into place and have a really nice tight fit now we can assemble the spinning logo so I'll stick my axle through the bearing and the other end is going to connect to that copper wait the logo will go on the other end here but since I design things so thin I'm not gonna be able to snap it into place I'm gonna have to go ahead and use some glue so of course I'm going with my default East 6000 adhesive and then I'll glue everything into place you can see the logo spinning but not as well as I'd like it to so I just went ahead and added some machine oil to the bearing and the whole disk just so that things would spin a little bit more freely I glued the rest of the parts and put everything in place and then I just went ahead and spun things around to make sure that it stayed free and I didn't get any glue inside of the bearings with a bit of fiddling I managed to get everything spinning freely while still keeping all the parts flush with the sides of my disc all right there it is my make anything Plinko puck like I said I'm gonna bring this thing to the matter hackers meet up next week on the 3rd and if you're going leave me a comment and it would be awesome if you made a coin for yourself to try out on the Plinko board so I'll put the dimensions in the description and even if you're not making it to this meet up matter hackers is planning to bring their board to different events like Maker Faire so it would be awesome if you made your own Plinko puck even if it's just for fun we'd love to see what you make so post it on social media tag matter hackers tag make anything and yeah it's a fun project so go ahead try it out and don't forget to stay inspired [Music] you
