Thangs
Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4928820.
Found the original Slim Hat Hook, when printed flat side down wasn't super robust. So I wanted something I could print "side-ways" to take advantage of the print orientation. That required filling in the sides a bit to get rid of bridging.
I also found, when used with my own fedora, it had a tendency to slip off, so I added ribs to increase friction. This one was printed for my wife's fedora, or should I say, "m'lady's" fedora.
I attached it with a command strip and a small wood screw into the back of the closet door.
