I needed to save some space in my kitchen rack by stacking my plates. But this came with the compromise of stacking my regular plates on the soup plates. So every time soup plates need to be deployed the regular plates needed to be moved first. Urgs.
So the idea was born to raise them over the regular plates. Now you ( I :-) ) can make it happen. Here is the solution!
The _base_version needs to be printed 4x, then connected together with the provided bolts to make one object. If you need a higher version with more floors you can stack them together (just print 4x the _addons_version). The size of my plates is 25 cm in diameter and they fit perfectly. I think bigger plates won't work but slightly smaler should be fine.
I printed my version without support and the result for the inner connectors wasn't great but works. So my advice is to use support to be on the save side.
