IKEA Bjursta Headphone Hook

This attaches to an IKEA Bjursta desk (or any desk that's 20mm thick). Designed for headphones with an extra wide band.

There are several similar hooks on Thingiverse, but they all either lacked a hook at the end (so my headphones would always fall off) or the attachment to the desk was not long enough, so my heavy headphones would pull the bracket off the desk.
