OpenSCAD - Imported STL file is "not a valid 2-manifold"

Recommended Posts

Posted · OpenSCAD - Imported STL file is "not a valid 2-manifold"


I'm trying to edit a .stl file I found on Thingiverse in OpenSCAD. I can import and render the file without problems. I made my changes and tried to export the file as .stl only to be told that is was "not a valid 2-manifold" and could not be exported.

After some experimentation I stripped the code back to just the import of the .stl followed immediately by exporting the .stl with no editing. Same problem. It also says that the .stl is "Simple: No" when it renders.

The .stl file in question is http://www.thingiverse.com/thing:17507. Side 1 and Side 2 models both have the same behaviour.

I tried sending the file via Netfabb and doing a standard "repair" on it, without it making a difference.

Does anyone have any ideas how to fix this? I'm trying to do this a treat for Easter, so I'm running out of time!

    I found a solution to my problem ... Netfabb Cloud.

    Owen mentioned this option in another thread so I tried sending the original Thingiverse Object to the Netfabb Cloud and it came back fixed. Now I can edit and export without any issues.

    I hope this helps others.
