1x1 unit Gridfinity compatible box for storing max. 25 spray paint clamps (or any other “sticks” that fit in 3mm holes). Hole angle increases towards the edges, so can also be used to hang miniatures to dry.

Works well enough, but there might be some changes. OpenSCAD sources coming later after some cleanup, and after I figure out the best way to distribute OpenSCAD code with extra dependencies from another project.
