3 Arm Fidget Spinner

thingiverse

This is a rugged fidget spinner that won't crack as easily as some more elaborate designs. The finger grips don't require pressing in, as they thread together seamlessly. The design consists of just two files: the Fidget Spinner Body and a male/female combo bolt and nut gripper. This spinner utilizes 5/8" diameter ball bearings for each of its three weights. The enhanced handles have printed flawlessly through Slic3r after adjusting the layer height to 0.1mm at the 4.5mm height. They also boast a larger diameter and thickness, allowing the spinner to rotate smoothly on a flat surface without any hindrance. The cupped grip has been eliminated, replaced by flat prints directly on the gripping surface - no support is necessary. The Rev B file of the spinner features slightly larger pockets for easier installation of the bearing weights (a little hot water helps) and enables free-spinning with minimal wobble.
