12-slot holder for standard 2oz (59ml) craft paints (Craft Smart, FolkArt, etc.). I designed this with a slightly tighter tolerance on the slots. It holds the bottles securely enough that I can grab the whole block off the wall and carry it to my desk without anything falling out—which turned out to be a game changer for keeping my workspace tidy. It’s standard Gridfinity (2x5), but as you can see in the pic, I’m running it on my Multiboard setup using David D’s Multiconnect shelves.
