Lithophane Light Box with USB LED touch dimmer

I really liked this model but I didn't like that the USB dimmer and USB extension were not supported and eventually fell through, into the box.

I included the original size for a 100 mm x 100 mm lithophane (3 mm thickness works well).

Also included is a 3" x 4" version (76.5 mm x 102 mm) for a lithophane I had made for a friend in this size.
