We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

Fix 3MF Normals StarForge 3D Modeling Software

Flip Inside Out Faces in Slicer Projects

Inside-out faces can hide in a 3MF just as easily as in an STL, and Fix 3MF Normals opens the zipped package in the browser to paint every inverted normal red. The download comes back remeshed with each face pointing outward, a clean mesh for 3D printing. Slicer settings, colours and plate layout stored in the 3MF are not part of it; StarForge 3D Modeling Software keeps only the geometry and returns a 3D Print STL File, free and with nothing uploaded, so no Blender session is needed.
