Geared Tri-fidget spinner

UPDATE 1/23/17
Added an option for a flat finger cap, if you want this just print 2 of the flat finger cap stl's no need for a shoulder as they are a part of the cap.


Yet another fidget spinner. These use a 22mm skateboard bearing and the finger cap is designed for an id bearing of 8mm.
Theres a model for ABS and PLA
These are TIGHT, I suggest printing everything at 100% infill and using something flat to press the bearings in with. A vise works if you've got one, otherwise, I just use the handle of a hammer.
The shoulder/finger caps go together very tight as well, I like to use a pair of channel locks to snap them together
Enjoy.
