I made these for some inexpensive "Cowin" bluetooth headphones. There's a centered, rounded ridge to reduce the flexing that could occur with 90-degree angles.

The PETG headphone hook in the picture has been in use for 4 months - no warping.

Measurements:

The desk edge is 26mm thick. The gap for the headphone to slide in is 18mm. The headphone band width is 45mm - the width of the headphone band in the picture is 31mm.
