This only needs four colors. The dark green is 2mm thick so less to no light penetrates when the LED are on. It gives it a nice shadow effect like the original image.
I would strongly recommend a slow epoxy when gluing. 5 or 10 minute epoxy is not enough time when preparing the lid to be glued.
Filaments used:
