When your working desk is not large, every extra bit of storage space is a help. My cup and headphone holder tackles two space issues. The cup holder part accommodates cups and mugs with a handle. The headphone simply dangles beneath your supported cup on an integrated hook.

This design is a variation to my popular desk edge bottle and headphones holder design previously shared.

To note, PLA will begin to soften around 60C, so take care if you like your drinks hot! Selection of higher temperature tolerant plastic (for the cup holder part) maybe wise, for example ABS and to a lesser extent PETG.

The cup/headphone holder clips to the side of a desk via an integrated "C" clamp. The holder supports cups up to about 90mm in diameter. The clamp adjusts to desk edge thickness up to 50mm. The "C" clamp screw bolt is an M12x1.75mm. I've shared print files for two bolt lengths to cover thick and thin desk edges.

To simplify the 3D printing step, I've made clamp and cup holder two separate parts. The two parts interlock and slide together to form a single unit.

I've covered the underside of my "C" clamp with a layer of non-slip material to improve the clamp effectiveness and secured the material with CA glue. Layer adhesion is normally the weakest part of a screw bolt, hence to protect the bolt, don't over tighten the "C" clamp.

My print is made in 1.75mm eSUN PLA+ black filament, with 0.2mm layer height and 15% infill on a Bambu X1 Carbon printer. Parts are by default orientated in the way I printed them on my printer bed.

I hope that you can find this print useful, too.

Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.
