I couldn't find any low-profile lithophane frames that accommodate the backlight board and a light guide so I designed this one. Good for a mailed gift - the whole assembly fits nicely into a USPS Priority Small Flat-rate Box, and should weigh no more than 340g (~12oz), everything included except a USB power source.
Required parts:
120x144 lithophane (slightly larger than Bambu's 144x108 format) with a 4mm thick frame-type border.
120x156 LED lithophane backlight board (original used this one). The measured thickness of the original was 1.56mm
2x M3x10 countersunk screws
(recommended) USB dimmer (example)
Recommended materials:
PETG used in the original frame for heat resistance. Probably not necessary if the LED board is 5W or less.
transparent PETG for the light guide
white PLA for the lithophane
Notes:
Use exclusive slicing tolerance
Original uses the small leg option, though the one-piece stand is tested and works well too.
The extrusion at the back of the frame was originally intended to be an attachment point for the stand, until I realized that the plug at the back + legs at the bottom are sufficient. I kept it in the model, as it can be used as a gopro-style swivel mount to attach the frame to something.
