Hat rack
thingiverse
This is a simple, over the door, hanging hat rack with hooks for 6 hats, but you could probably double up on them too. Pieces do not connect automatically, I just used super glue. My doors are not super thin, but If somehow your doors are super thick, the hanging part may not fit over the top. Small amount of supports needed for the overhang of the hook pieces.
