Fidget tri-spinner curved

This is a tri-spinner fidget toy for 4x 608 bearings. Print it at 100% infill. This ensures a little bit of extra weight as well as extra strength (like when you drop it on the floor accidentally).

Optionally you can print the spinner center piece twice to fit in the middle bearing for improved handling/holding.

Tip to improve the bearing friction: remove the caps from the center bearing and rinse out the grease, then apply a couple of drops of sewing machine oil and it will spin like crazy! ;)
