Converting 3MF (3D Manufacturing Format) to Wavefront OBJ

3MF is a modern 3D-printing container that can hold color, multiple parts and print settings. OBJ is a simple, universally editable mesh format. Converting 3MF to OBJ gives you a clean, portable mesh you can open and edit almost anywhere.

What's kept and what's dropped

Mesh geometry is exported into OBJ. 3MF extras — color, multiple build items and print metadata — are flattened, since OBJ stores geometry (and optional materials) only.
