3 Arm Fidget Spinner

thingiverse

This is a sturdy fidget spinner that won't crack as easily as some of the more artistic examples. Also, there is no need to press in the finger grips, as they thread together. Now just 2 files: Fidget spinner body and a male/female combo of a bolt and nut gripper. This spinner uses 5/8" diameter ball bearings for each of the three weights. The improved handles have printed great through Slic3r with changing the layer height to 0.1mm at the 4.5mm height. Listening to feedback, they also have a larger diameter and thickness, to allow the spinner to rotate while resting on a flat surface. I also removed the cupped grip and print them flat on the gripping surface-- no support needed. The Rev B file of the spinner has slightly larger pockets for the bearing weights to install easier (still need to warm up with a bit of hot water), and to free-spin without too much wobble.
