A sideways pointing headphone hook, if for some reason a straight headphone holder is not an option.

If you need the one pointing to the right, just mirror it along the x-axis in the bambu studio.

If you have any ideas how to improve it, I'm happy to listen.

Note: the maximum desk thickness is 30mm with this version but I can easily create one accommodating a thicker or much thinner desk.  

Different screws are also an easy upgrade, so just ask if you need one, I'll try and get to it asap.
