I'm sorry if this is an dumb question, I am a beginner. My goal is to print my sketchup model, without anything on the inside, since I won't see it. I've imported the STL export, after getting rid of as much geometry as I could in that app. I want to delete all of the internal geometry, only an outer shell. The model is too dense to do a shrinkwrap or remesh modifier. What can I do?
