Put one to four photos on the walls of a closed box lamp. One photo repeats on all four sides; with more, they go one to a wall. Set the width, depth and height, the thickness range, an optional base plate with a hole for the LED or cable, and a raised frame around each photo.

Up to four, one per wall. With one photo every side is the same; with two, opposite sides match.
Put a cool LED light inside: set a base plate and an LED hole in the generator so the cable or light fits through the bottom. Avoid hot bulbs, which soften PLA.
No. Printed upright, the walls are vertical and the top is open.
Use 100 % infill, a 0.10 mm layer height (0.08 mm for the finest detail), a slow speed of about 30 to 40 mm/s and the fan at 100 %. Any gap in the infill lets light leak through unevenly. The full table is in the guide.
