Ball Bearing Fidget Spinner

cults3d

This is a simple and fun fidget spinner I created that utilizes one ceramic or metal 608 bearing and five 15 mm ball bearings. I'm also providing a "Murican" version that incorporates 1/2" ball bearings for my American brothers and sisters. Every part must be pressed firmly into place. It's a bit tricky to get the ball bearings in position, but I found it easiest to set the spinner flat on a table with one of the ball bearing holes hanging off the edge. Next, place a ball bearing over the hole and use a piece of wood or something hard to press it firmly into place with some force. Mine didn't break, but if yours does, increase the infill density or try a different filament. It's best to use PLA or PETG so as to minimize warping issues. Once that's done, press in the caps, give it a spin, and enjoy endless focus and concentration.
