Lithophane heart light box

Lithophane light box that projects cute love hearts onto the wall. Lithophane measurement150mm ( Lithophane measurements have been added into the photo's ) Light box MeasurementsH 160mm x L 160mm Needs to be printed flatNo supports neededI use 10% infill but its up to the individual on how much infill they would like to use.For black PLA I use 2 walls but for other colours I use 3 wall loops as I don't like seeing the infill pattern shine through when the LED is turned on. I use a 1metre LED strip that can be purchased from TEMU, SHEIN, WISH.
