Free public beta

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

Model source

Upload a local 3MF or STL file. 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

Was your model not fixed?

Send the original 3MF or STL file directly for review.

Result

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

Load a file to see the repair details.

Upload a 3MF or STL file, 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.

Simple file upload

Upload a local 3MF or STL file directly from your device.

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.
