Since I needed a new holder for my headset and also like to play World of Warcraft,
I combined the two and created a Horde wall mount.
There are 2 versions which differ only in the length and the screw holes.
The holder for the headset has only one screw while the holder for the spool has 2 screws
(better hold and torsion-proof).
The length for the headset is 65mm and for the spool 93mm
(spools up to approx. 85mm fit).
