Rubics Cube stand that spins, what else is there to say?

Place top segment upside down for printing. no supports needed.

Uses a single 608 ball bearing, I suggest a high speed fidget spinner grade bearing for maximum spin, such as: this one from amazon.com

I had some sticky feet so made some holes in the bottom and uploaded a TPU version of the foot, this might work for you, and if not, there is also a TPU ring version. 

May be a little difficult to learn how to spin without throwing the cube, but if you learned to solve the Rubics Cube, you can learn how to spin it, I believe in you!
