OBJ → 3MFOBJ to 3MF Converter
Preflight OBJ models for additive manufacturing with watertight checks, unit normalization, and export guidance.
Why this preset
- Runs watertight and triangle-count validation before export
- Applies printer-friendly scale and centering defaults automatically
- Keeps texture references so downstream repair tools stay in sync
Native 3MF export ships soon. For now, use the GLB bundle with matching scale.
