I decided to make a case for my Note 4 and put my sign on it. You can print only file 1 for a single color or you can do a dual extrusion print with two colors and combine the two files in Cura or Repetier Host. Also you could print each file seperate and glue or weld the extruded text in the case. If your slicer does not slice correctly it is because of the thin walls of the case model. Cura and Repetier Host should automatically cheat the wall thickness to 0.4 or whatever your nozzle size is. my personal website is on www.FourDeX.com
