I have a bunch of miniature paints, but only a narrow slice of wall to store them. So I made a paint holder, and decided to make each row a tray that can pull out (in case I need a lot of similar colors, or the paints I need are too high up on the wall to reach while sitting down).
Here’s the whole thing on the wall:
Here’s some trays on the desk:
Each rack on the wall holds four trays, and is designed to mount with 3M picture-hanging Command Strips, and be nearly hidden behind the back braces:
I modeled it in OpenSCAD, so a few tweaks to some numbers, and I can generate different-sized trays and racks:
The whole thing was done with medium draftboard, and I used Sobo craft glue to stick things together (it was nearly friction-fit, but I wanted to make sure these were solid). Overall, works pretty well; and when I get more paints, I can just print up another rack and stick it to the wall somewhere.
