A light box made for a square 1078x1078 photo from Instagram converted to a Lithophane.

Printed lithophane is 100x100mm.

Note: Some photos are not accurate to this specific print size. Some photos show a rectangular box. These are just photos I had that show the LED placement and lithophane insertion slot. The same design style is used for the square box.

LEDs used (although any LED strip will do): http://a.co/fTXi60s
