Big Ball Fidget Spinner

thingiverse

Started with 2ROBOTGUY's Tri Fidget Spinner Toy, but instead of using three more bearing sets for the weights (which are expensive, right?), I used some 5/8" ball bearings I had left over from the castors of a robot. They add a lot of mass, and will rotated in the housing giving another "fidget" activity along with spinning. You need to heat the body with a hair drier or hot air gun and press the ball in (not too hot, or it will warp). I also designed the finger pads from scratch. I've tried a couple and of nothing worked the way I wanted.
