This is just a quick design of an under desk headphone holder. It should hold a headphone with up to a 70mm headband. 

There is also a quick printing drill guide to help pre-drill the holes. In the pics it looks like the holder is angled downward but that is just some camera lens distortion or something since it is parallel to the desktop.

There are two versions, a V12 and a V11.  The V12 has a taller lip and the V11 has a shorter lip, with the option of adding a TPU bumper.  I  would go with the V12 unless your phones have a very thick headband ( > 20mm).

Print with supports (they will be minimal) and see pics for a suggested orientation (which is 45 degrees). The drill guide is optional but may help with positioning it under a desk.
