Hat rack

thingiverse

This is a straightforward, wall-mounted hat rack that holds six hats, though you can easily double up on them if needed. The individual components don't click together by themselves; I used super glue to hold them in place. My doors aren't incredibly thin, but if your doors are unusually thick, the hanging piece might not fit snugly over the top. A minimal amount of support is required for the hook pieces' slight overhang.
