Why the subtractive rather than additive method? Machined spinner bodies are much better in the final results than most consumer 3D printers. They then generated the machine paths and machined from blank stock material using a Othermill Pro. Here you can see the rendering in Fusion 360 making the part look real. The the cuts and insert of a purchased bearing and the pennies as weights. Garin led them through developing the features with a sketch, patterning, and extruding.
It was amazing to be a spectator in the class and hear the comments and questions. For many this was their first ever exposure to design or Fusion 360. The kids had Fusion 360 running on a laptop and followed along step by step. This was the future of making the makers of the world type of class. Garin developed and led a class to walk the kids through the design of a fidget spinner and the machining of it in Fusion 360. One of those activities was designed and led by Garin Gardiner. A couple weeks ago at the Autodesk Lake Oswego Oregon office we held our annual Kids at Autodesk Day, where employees brought their children to work where we have several activities for them planned. With a little bit of effort you will be able to push the bearings into the holes.Fidget Spinners are all the rage, whether you love or don't care for them, they are here. I printed them in ABS material with my UP Plus 3D printer and it took 1 1/2 hours to print. Once you have downloaded them 3D print them. You can download them by clicking the buttons below. Once you have the right bearings it’s time to download and 3D print your fidget spinner. For a future mod I plan to take out the seals and clean the grease out. The down side is that I suspect the grease has a braking effect on the spinning, so the spinner does spin too long. The bearings I bought are sealed, and I assume there is grease inside the seals. Other brands will offer the same size bearing so compare a few few for the best price and quality. In other words the inside diameter is 8mm The outside diameter is 22mm and the bearing is 7mm thick.Ĭlick on the image above to see the SKF specifications page. The correct bearings are SKF608, or normal skateboard bearings. If you are one of these fortunate people, you can download the 3D printable STL files right here and 3D print your own! First get some bearingsīefore you 3D print the STL files you sould get the right size bearings. The third option is for people who are lucky enough to have access to a 3D printer. You can go out and buy any shape or form of fidget spinner that some salesman or hawker is likely to flog, or make your own. So if you want to jump on the bandwagon you have a few options. Either way, it’s happening right now and the whole world is fascinated by these things. Perhaps you think the Fidget Spinner craze of 2017 is silly.
