3 part print. Print the front facing down, back facing up and stand is your call. I have it on it's side. It's already in this orientation in the 3mf file. There is a 4mm hole located in the back plate for the cord.
The light boxes are by design very thin. After printing you must let the plate completely cool so when you flex the plate it comes off easily. Whatever you do don't pull up on it or it may separate.
