Attempting to print another nose cone, this time using a slightly different approach. I'm using Simplify3D. The bottom / base of the print will use both an outer perimeter (2 shells) and a thin infill with a single inner shell. After the transition, I want to switch to an outer perimeter only print (2 walls). I have set the infill to 0%, and setup two different print processes each defined to only print at specific model heights. The problem is that I can't find a way to only print the outer shells, and not the inner shell. The model is drawn with a .125" wall, and that is a bit thick. I know there is a way to do it, but I can't find the correct combination of settings.
