Lithophane light box
thingiverse
This is a light box for mounting a 100mm square by 3mm deep lithophane, with a 2mm frame. There is a hole in the back to fit a micro USB step up power supply, which powers 3 5cm 12V LED strips hot glued to the back of the box to illuminate the image. I have included the original model to allow you to resize it for an image of any dimensions. I used this USB power supply, but the cutout is generously spaced and should accept most similar boards: https://www.amazon.co.uk/gp/product/B071H9NRTW/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 For LEDs use any 12V (or other voltage as the supply is adjustable) LEDs you can get hold of. I usually use 5050 cold white as I find they provide ample light and the colour works well with the eSUN PLA+ cold white I usually print in.
