Wasn't satisfied with any of the headphone hangers i found on here before, as all of them seemed to have an overhang on the front of the screen which would have impinged on the viewable area of the screen (or would have seemed to anyway).
This gets secured to the back side of the monitor with a square of strong double-sided tape or some other adhesive, and does not require supports.
I needed it to be wide enough to hang my Razer headset, and works quite well.
I printed it with 5 walls and 40% infill, which was probably overkill, but it is very, very sturdy.
