M10 Fidget spinner
thingiverse
I've been creating a few spinners for my son and daughter found on thingiverse. Now it was time to try designing one by myself. It's using a standard 608 bearing and 3 M10 nuts. It's a bit bigger than most spinners, not ideal for small hands. I opened the bearing, cleaned it with benzene, and the result was astonishing. This spinner kept going for 3 minutes and 15 seconds - I'm impressed! I use the caps from this spinner by Mr_MinerAl on thingiverse: https://www.thingiverse.com/thing:2315392. They work really great and lock nicely in place with no need for glue.
