This model consists of all the letters separated. Each one measures approx. 16cm.
Each one fits into the next. The tolerance given between pieces is 0.35mm so it should work fine for most prints.
I recommend using adhesive between the letters to ensure a secure hold.
I printed the boxes with a 0.6 to 0.4 layer height nozzle. This gave me very good printing times (2-3 h per box). The lids I made with a 0.4 nozzle and 0.2 layer height.
I have used approx 2mts of 5v led strip but you can use any led you like.
Layer height : 0.2 - 0.4
Infill : 8%.
Supports : NO
