Lithophane Fully Printed Frame

**Printed Lithophane Frame**
I decided to make a series of lithophanes for Christmas gifts this year, with customized pictures for each one. I custom designed a frame, light box, back plate, and power box that would fit perfectly, and assemble together for a nice clean look and finish. Here's what you'll need:
* A printed lithophane - 120mmx170mm, with a 7.5mm width (see below for details on making lithophane)
* Two M3 hex nuts
* Two M3x12mm button head bolts
* 12v LED lights (I used these - https://www.amazon.com/gp/product/B012FFZ4QM)
* Power switch (I used these - https://www.amazon.com/gp/product/B0928VLVTH)
* 12v power cord/plug (I used these - https://www.amazon.com/gp/product/B01HDAIAGU)
* As an alternative, I also tried these plugs. They were a little bigger, and require the power box that is labelled "Larger Plug": https://www.amazon.com/gp/product/B077Q2M69Q
* And I bought these cords, which take up a little less room than the original ones listed above: https://w
