Screw-In Headset Hook

thingiverse

If you don't mind making holes in the underside of your desk, this mount will attach securely and look clean. Beneath the hook there is a large slot to run cables. (as seen in the last picture) Clamp designs usually deform over time and no matter the design, the part on the desk surface looks clunky. With this, you'll hardly notice the hook is there except when you need it.
