Tri-Spin

thingiverse

More Fidget spinners! This triple sleeve bearing spinner prints in place and can be spun on each of its three printed bearings, with the more it's spun, the better they wear in and spin! Or try some lube for a smoother ride. It may not spin as well as one with an actual 608 bearing, but it's way more exciting to use! The print is relatively easy-going and can be printed on any 3D printer with a well-levelled bed. A heated bed isn't necessary, but it does help. The spinner pictured has an infill of 40%, but if you want more momentum, increase that to as high as possible!
