Headphone Hook for Drawer

This is a simple headphone hook that clips onto the front panel of a desk drawer.
I designed it for my specific setup, where:

the drawer front is 15mm thick

there is a 3mm gap between the drawer and the underside of the desk

It works great for holding my headphones and keeps my desk tidy.

I’m sharing the 3MF file and the FreeCAD source file so you can adapt it to your own desk if needed.
