Free public beta

Repair 3MF and STL files for cleaner 3D printing.

Model source

Load a local 3MF/STL file or paste a MakerWorld link. STL files receive non-manifold edge repair only.

Drop a .3mf or .stl file, or select one

The file is checked before the repair starts

Result

Slicer settings and non-manifold geometry detected in the file.

Load a file or download one from MakerWorld to see the repair details.

Upload a 3MF or STL file, or paste a MakerWorld URL, then review the repair report before downloading a corrected model. 3MF Fixer targets non-manifold geometry, STL repair, and slicer settings that can break 3D printing workflows.

Free tier with ads

Banner slots are reserved now. Rewarded ads can later unlock extra free repairs after AdSense approval.

Flexible file input

Start from a local 3MF/STL file or paste a MakerWorld URL when a profile download is configured.

Non-manifold repair

STL files focus only on non-manifold geometry. 3MF files also keep slicer fixes available.

Clear repair report

See the edge count before and after, plus every slicer parameter that changed.

Web-based repair

Built for makers who need a fast fix, not a full CAD workflow.

The first public version focuses on common 3D printing failures: non-manifold STL geometry and incompatible MakerWorld/Bambu 3MF settings for Anycubic Slicer Next.

Premium plans

Free now, paid plans after real usage data.

The free version will keep banner space and optional rewarded ads. Premium will remove ads, raise limits, and unlock heavier repairs once processing cost and quality metrics are measured in production.
