I have a model I want to print that has multiple layers of internal walls. They are useless and can’t be seen in the finished product, like a hollow cylinder inside another hollow cylinder.
I can’t seem to figure out how to prevent the slicer from including those useless parts. I’ve tried with Cura and PrusaSlicer. Is there another tool I should be using for this?
It’s possible that this model was never meant to be printed (or it wasn’t intended for a typical FFF-type printer). The people who have said you need to edit the stl file directly appear to be correct. Once you’ve got it edited, you may want to make the fill denser to prevent anything odd from happening as you print.
