Level 4 Menger Sponge

thingiverse

A mind-blowing Menger Sponge printed out in just under three days on my Prusa i3 clone, with precision settings at 0.1mm layer height, 100% infill, and conservative motion controls. This large file is massive - make sure you have plenty of memory available and be patient when it loads up if you open the F360 file. It's not even close to being optimized; I'm still a complete beginner with F360 software. Simplify3D had no trouble printing out the .stl file, though. The undersides of those four giant overhangs at the top level didn't turn out great without any support. My printer was finally able to bridge the gap just like a spider spinning a web, but the underside of those parts don't look very pretty at all. You might want to add custom supports here for better results.
