Want to print this model https://www.thingiverse.com/thing:4013242 and the maker recommends on only use infill in the bottom and the top. Using Cura 4.7.0.
Then I create an eraser cube, size it so everything execpt the bottom where I do want to have infill is covered, then change the setting eraser cube to "Mesh Type: Modify settings for overlaps" and "infill mesh only" and finally "Infill density: 0%"
When I slice it, in the preview it looks ok, only bottom has infills but not the walls. However, printtime and material usage is much more than if I have infill everywhere.
Why is that?
