3D model printing STL

[notallbad]

It would be great to have the ability to 'Export' directly to .STL format for 3d printing purposes.

Seem to be having difficulty when exporting as .obj file and too many 'manifold' issues.

Have you found a way to print it ? I am having same issues, slic3r just do not like what I get when I convert obj to stl.
