Tiny(-ish) Tri-Spinner

Center bearing is the MR74 (4mm ID x 7mm OD x 2mm H)
Ball Bearings are 12.7mm (1/2")
Buttons included

Tolerances were pretty tight for me, so some manual adjustment will most likely be necessary

I've included the .obj files for those who want to tinker

At the time, it was one of very few spinner designs not using a 608 for the center bearing
