I designed a quick hook model to replicate some hooks we already had that were getting a little old. This simple design hooks over the top of a standard width interior door (~35mm) and is a nice snug fit to keep it held in place. Super handy on closet doors to give you a place to hang a hat or sweater that you might use often, but not all the time. The design includes a screw hole on the back in case you want to make extra sure it isn't going to go anywhere. Should be strong enough to hold most clothing items you can throw at it.

I recommend printing out of PETG for the added flexibility and strength. The provided print profile includes a brim, but if you are using your own settings I strongly recommend a brim to ensure proper bed adhesion. I had trouble even using the SuperTack build plate, but your mileage may vary.
