Simple Under Desk Headphone Hook

6.5mm screw hole.

Easy to print, rounded edges. Relatively thin (4-6mm) but strong enough for its intended usage. Has a full inch of height clearance when attached, which should be enough for most headbands to slide through. The length of the resting area is approximately 2 inches long and 1 inch wide.

Includes a slot for headphone wire management. Works well for when you have a long length cord and want to keep the wire from ending up in the wheels of your office chair, so you only pull the length you need through the hole and the rest will comfortably sit underneath the desk away from your wheels.
