Results from the “Check” command:
This is a bad mesh.
Here is what is wrong with this mesh:
Mesh has 248 non manifold edges.
Skipping face direction check because of positive non manifold edge count.
Mesh has 4348327 pairs of faces that intersect each other. This can cause problems if you’re doing mesh boolean operations with it.
