This is my first lightbox I have ever made and it looks awesome! I have made 2 holes for the led cable that is 5mm wide, if you want to make it bigger you can easy make a bigger hole or a square in your slicer.

Place all “Plate 1” files together and print and then “Plate 2” together.

Lower the walls to 1 and low infill on the “sidelight” for nice sideglow.

Let me know what you think!
