Wanted a stand to hold these Stanley Drinking Cups (holding the rejects in the picture so don't judge me! lol). In typical over-engineering fashion, I decided to make it rotate with a bearing.
 

It's made for Amazon.com: 50 PCS 608-2RS Skateboard Bearing, 8x22x7, Sealed : Sports & Outdoors style of bearing.  I've not tried but there are printed bearings that may work also, example: 608 Bearing by tjhoven74 - MakerWorld
 

You can choose to skip the base and the bearing, and it just makes a nice stationary stand.

I only printed the smaller of the two since I didn't really need a big one, but figured somebody might. The dimensions of the bearing hole and the shaft on the base are the same between them. If you print it and there's a problem, let me know.
