5/8 Fidget spinner

thingiverse

I'm excited to finally get my hands on one of these fidget spinners. I've seen them everywhere and always wanted to try one out, but the only bearings I had lying around were 5/8 OD and 1/4 ID, measuring 15.8 and 6.35mm respectively. So, I quickly whipped up a design in Fusion 360. The result is a functional fidget spinner that holds US nickels as weights, and it even prints perfectly with a press-fit assembly on the first try. To print this design successfully, I recommend orienting the caps flat-side down. Unfortunately, Thingiverse often gets my STL files oriented incorrectly, so be sure to double-check your settings before printing. I've included an IGES file for you to modify as you see fit. Keep in mind that I designed this quickly and didn't take the time to chamfer any edges or add any extra features. However, with this file, you can easily make adjustments and create a design that suits your needs. If you're working on a smaller scale, consider shortening the overall length of the spinner to accommodate smaller hands.
