Lithophane Frame

A frame for lithophanes. Designed to work with 5V LED strips such that it can be USB powered.

Also provided as OpenSCAD file to allow for customization.

To generate a lithophane to insert into it, resize your photo to 4200 * 3150px and paste it into the provided template. Then upload to http://3dp.rocks/lithophane/. Make sure to use the following settings:
Maximum size: 145mm
Thickness: 3mm
No border, base, etc.

The frame includes a housing for a 15*21mm rocker switch. The switch_housing_dummy.stl file is provided specifically to test if your switch fits snugly without printing the whole frame. If not, the attached .scad file can be modified but a model of the frame without the switch housing is also provided.

After printing, attach and wire up white (5V if you want it powered by USB) LED strips as shown in the photos. If applicable, wire in the switch and finally connect wires 1 and 4 (+5V and ground) of a usb plug to the appropriate wires for the LED strips.
