50mm Lithophane Box

This lithophane box accepts 5 lithophanes (50mm x 50mm, 3mm thickness). I generated my lithophanes [here](http://3dp.rocks/lithophane/).

Steps:

1. Print the two STLs (TopV3.stl and BottomV3.stl)
2. Insert the lithophanes into the top (they slide right in). The top is friction fitted in.
3. I bought some [USB LEDs](https://www.amazon.com/gp/product/B00TGTB4HO/) and I cut an old USB cable. I soldered the 5V and GND wires to the USB LEDs.
4. Attach the USB LEDs to the bottom, I secured mine with M3 nuts and bolts, you can use double sided tape or hot glue.
5. The top slides right into the bottom
6. Connect the USB to a power source and you're done!
