Very nice! I have the same locking Rubbermaid lids and I use an accoridian stainless plate holder for them. It works quite well, but this looks even a little bit better and is a perfect unnecessary 3d printing project to add to my list. Assume the medium lids (second shelf down on left) are with the regular stl, not the “big” one? Assume PLA for this? Doesn’t really need to be PETG does it? Agree no supports needed? 15% infill?

Im excited to try these holders though. I’ve been photographing different items in the kitchen, using photo to stl conversion and making placeholders for things with that technique - so yes, the obsession is real.
