A simple headphone design that can be mounted to the wall using 2 screws or via double sided tape. There is a groove in the back of the mount that fits standard VHB double sided tape.
I have used it for holding headphone hats and even have some in the shed for my ear protectos and face shield.
Plate 1 has ironing turned on and plate 2 has ironing turned off. Both have the same strength settings that I have been using for over a year so has been well tested to be strong enough even in PLA.
I also sell the printed items on my etsy shop for anyone who doesn't have a 3D printer:
