It spins! It might help relieves stress! That's about it. Have fun!

3/31/17 update: I changed the edge from a semicircle to a rounded rectangle (fillet radius 3.5mm -> 2mm) to make the print a little cleaner and better looking when printed.

the cap press fits into the center of the bearings and should ride above the bearing by 1mm, keeping it clean and providing a good grip. It's available with and without a divot.

I would suggest using either a wall thickness of at least 1.2mm or a 100% infill. The solid infill makes it a bit heavier but it doesn't break like the old ones with less infill.

Swapping the filament color mid print looks great, see the photo I've included!

Edit 4/30/17: I've uploaded my new designs for the spinner caps. One is flat, one is concave, and one has concentric rings.
