Ball Bearing Fidget Spinner

thingiverse

I designed this simple yet fun fidget spinner using one ceramic or metal 608 bearing and five 15 mm ball bearings. I also included a 'Murican version featuring 1/2" ball bearings for my US-based brothers and sisters. Every part must fit perfectly together, pressed in place without any gaps. It can be tricky to get the ball bearings into position, but I found success by placing the spinner flat on a table with a ball bearing hole leaning off the edge. Then, carefully place the ball bearing on top of the hole and press it in using a hard object like wood. Mine worked fine, but if yours breaks, try increasing the infill or switching to a different filament. It's best to use PLA or PETG for this project to avoid warping issues. Once assembled, simply press the caps into place, give it a spin, and enjoy the distraction-free experience.
