A sturdy headphone/headset holder with a single screw hole for mounting onto a wall (in a stud or with a drywall anchor).

My headset is a Plantronics Gamecom 780 and it was designed specifically to fit that without much wiggle room. Simply expanding the model on the Z axis (making it taller) would allow you to fit a wider set of models if you wish.

I printed with 210 degree white PLA with low in-fill and low quality and it came out pretty good!
