Ball Bearing Fidget Spinner

This is a simple and fun fidget spinner I designed that uses one ceramic or metal 608 bearing and five 15 mm ball bearings. I am also including a 'Murican version that uses 1/2" ball bearings for my brothers and sisters in the US of A. Everything must be pressed fit together. It's a little tricky to get the ball bearings into place. I found it easiest to rest the spinner flat down on a table with a ball bearing hole leaning off the edge of the table. Then place the ball bearing on top of the hole and use a piece of wood or something hard to press it in with some force. Mine didn't break, but if yours does, increase the infill or try a different filament. It's probably best to use PLA or PETG so as to avoid warping. After that, press the caps in, give it a spin, and never be distracted by anything ever again.
