Headphone holder for desk/table

This is a simple hook to hang a pair of headphones off the edge of a table or desk. The opening that holds onto the table is designed to be slightly smaller than the table is thick so that the deformation of the plastic keeps the hook on the table. The hook should be a good tight fit on the edge of the table so it doesn't move around.

The hook is currently designed to hold onto a 16 mm (approx. 5/8 inch) thick table. However, I included .ipt and .step files so the dimensions can be edited for
