LumaDock — Gridfinity Phone Dock with Lithophane Photo Panel

Your photo, glowing behind your phone — now on a true Gridfinity base.

This is the LumaDock v2, rebuilt on a 2×2 Gridfinity base. The dock drops into any standard Gridfinity baseplate (footprint exactly 84 × 84mm), holds your phone in a 20° cradle while it charges, and carries a backlit lithophane photo panel behind it. An LED tea light in the panel's rear cavity makes the photo glow — no wiring, no electronics.
