Lithophane lamp - 4 frames

I wanted to give away some lithophane lamps for Christmas, so I designed my own 4 pane lamp. It's designed for 100x130x5mm lithophanes, and is able to easily swap frames in and out as you make more in the future.

It uses a 59 lumen LED lamp (link below) which is just about perfect. It won't light up a room, but is pretty well visible even in a pretty bright room. Wired up with simple 2.1x5.5mm barrel connector pigtails and a standard 12v wall wart. About $5 of electronics per lamp
