Combo headphone hook holder and a single SD card holder.

I've originally made the hook for my Koss Porta Pros, which have a very narrow headband. Due to popular demand, I've also added a version for wider headbands. And there's also the Fusion360 drawing, so if needed, remixing the hook should be fairly easy.

Optional cable hook

I suggest printing the normal version. But if you want to have a cable hook on the bottom → the alternative version has an extra piece that serves as a cable holder.

Print instructions

The basic version prints completely without supports.

Only the cable hook needs support.
