Lithophane Frame

Designed in Fusion360, a full frame enclosure for lithophanes.
You can print it in any material, but I guess PLA will suffice, and you should pick a dark color, so you don't get light bleeding from the back, instead all of the light shines through the lithophane.
I designed this to work with simple LED strips (100mA / meter) + a 9V battery, which should give around 10 hours of up time (you need about half a meter of LED strip).
I wanted to also add a barel plug in the back so it can be run from 12V power supply, but I'm super busy lately, maybe in the future. Keeping this as work in progress till then.
The lithophane snaps into the frame easily, left a little arm at the bottom to secure it with a screw but I don't think it's really necessary, as for the lights, you just have to cut and solder a few LED strips, a switch, and a 9V battery plug.
(Wiring = all negative leads from LEDS together, and straight to the battery's negative plug terminal, all positive leads from the LEDS toge
