Prints perfectly. no supports required.
A lithophane box I knocked up to hold a 120x80 lithophane.
I designed it to hold a string of 48 battery operated LED fairy lights that I had left over from Christmas.
There is plenty of room in the back to hold the excess cable, the battery pack will sit outside the unit.
I suppose you could also just string together a series of 5mm LED diodes and populate
any holes that you wish. my LED's have a Built in diffuser and as such wont cause hotspots at the distance that i have chosen.
SLOW first layer there are a lot of holes to lay down in a short space.
