This is a hook (actually three hooks) for hanging towels. Contrary to ordinary hooks, no parts are sticking out which means you will not hurt yourself when you accidentally bump into it.

Designed to be printed without support.

Mounts to the wall using hidden screw-slots on the backside. Use two screws with 6mm head, 3mm(max) diameter, 50mm apart.

Update 2022-03-14: Added fillet in the hook holes.
