Gravity-Activated Phone Stand

A phone stand that works with physics, not against it.

This gravity-activated stand uses your phone's own weight to lock it in place. Drop your phone on the pedestal and the rack and pinion gear system does the rest—arms grip from the sides automatically. Pick it up, and it releases. Simple mechanical engineering, zero complications. The design adjusts to any phone width and works perfectly with phone cases and USB-C chargers.
Why This Design Is Awesome:
✓ Prints Like a Dream - Optimized for any FDM printer with basic PLA
