Micro Fidget spinner
thingiverse
I had a few of very little bearings lying about but not enough for the "Trini Fidget Spinner by SkyDro," his requires four. And the way he designed his I could not use steelies without it coming apart, so I took to fusion360 and made this one it is about 2% larger than his, you can still use all bearings in it or use 8mm steelies like I did. The cap uses a 3mm screw, one can either screw it together or pin it. This was mainly a test for my fusion360 skills and printer accuracy. It works great and is micro. Who doesn't like to miniaturize things?
