This is a modular finger nail polish holder I designed for my wife. It was made specifically for her favorite brand of finger nail polish bottles (Olive & June) but should work well for any similarly sized cylindrical bottles. You will need 2 sealed bearings measuring 20x42x12mm to press fit into each level of bottle holders, I ordered mine from Amazon (linked below) but feel free to source from wherever. Each level of the holder will hold 12 bottles and you can stack them 3 high. You could try to stack more but it bay become less stable as it gets taller. I would recommend printing additional holders if you need more than 36 bottles of storage.

Also, yes you can use this to convince your wife to let you buy a 3D printer. I can confirm because it worked for me ;)
