If anyone wants to look at the problematic stl, see link below. Also see what Netfabb thinks of it further below (not good).

I could resolve the problem with a newer version from OpenScad which in deed has the manifold feature within the settings.

Hi, I'm developing my file fixer further. There appears to be 140 degenerate triangles in that file. I know where they are, am getting co-pilot to write the code for meshlab to auto fix them.
