This is my designed paint spinner. I used 5 skate bearings for the wheels inside the bottom.

This is modular. I have one printed 3 units tall and one that is 4 units tall. 5 would likely still be sturdy.

Per rack you need:
1 Bottom, 1 Pillar Base, 5 Wheel Pegs, 1 Wheel Plate, and 1 Pillar Cap.
Per rack level you need:
1 Pillar and your choice of Paint Disks.

The Small Bottle Paint Disk can store big bottles about every 3rd bottle with small in between.

The Wheel Pegs I print standing on end.
The Pillar and Pillar Base I flip upside down and print with supports set to "Touching Buildplate."
The Pillar Cap I print with supports set to "Touching Buildplate."
The rest shouldn't need support or any rotation.
