Free STL repair
Your slicer says the model has holes, flipped faces or open edges? Choose the STL and get a cleaned-up copy. It all happens in your browser: your file is never uploaded.
Nothing is sent anywhere. Keep your original: this makes a new file.

What was done
Left as it was
What it fixes, and what it cannot
- Fixes: points that sit on top of each other, collapsed and repeated triangles, triangles facing the wrong way, a whole model that is inside out, holes (including missing faces), and tiny floating specks.
- Does not fix: surfaces that cross through themselves, edges shared by three or more triangles, walls too thin to print, or very large complicated holes. If the result is still not watertight, the report says so instead of guessing.
- Closing a hole fills it flat from the middle of its edge. That is right for a missing flat face and rough for a curved gap: look at the result in your slicer before a long print.
- The file is not scaled, moved or simplified. Units stay as they were.
