Retractable headphone holder
thingiverse
Retractable headphone holder mounts discreetly under your desk, out of sight until you need it. Pull the lever to extend the holder and use it for your headphones or any other small item. The gear and rack mechanism makes it easy to pull and push the rack. Optionally, attach a spring to the lever to lock the rack in place, requiring a gentle tug on the lever to release it. For best results, try out GCode Simulator before printing to ensure a smooth process.
