This is a light box for a single 100x100x3 lithophane. It has a hole in the back to fit a 12mm female power jack. I also use a dimmer dial because the 12v led strip I cut from is too bright at full power. I lined the back wall with a square frame of led light strip. STEP files included in case you want to modify it for a different light solution.

I'm printing with a .8 nozzle .3 layer height 3 top, 3 bottom, 2 perimeter. Prints nice, clean and fast.

Please ignore the terrible quality of the actual litho. It was made off of an old yellowed black and white photo that was in pretty bad shape.

Power jack I used: Description says 11mm mounting hole, but I couldn't fit it in so had to go 12mm. https://www.amazon.com/gp/product/B083VSXHZF/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
