Weird holes in model?

I have tried slicing this with repetier/slic3r , cura and S3D. All show strange holes around the body.
And drillholes inside the model.
No errors are reported in these programs.

Autodesk 3d print utility and netfabb think it is ok with no errors.

So i loaded it into Blender, and it seems to be ok. It is pretty lowpoly.

When i print it, there are 4 holes in the body, sides are weird also..

What is wrong?

The model is manifold however there is a problem with the geometry itself.
The walls have voids in them. The holes on the outside happen because the wall thickness is too thin on those spots to print.

To view it more clearly I temporarily changed the extrusion width to 0.1 mm.

ok, well i dumped the model and printed another instead.

I have lately begun to run all models through autodesk's 3d print utility, it is really good at repairing models automatic. Much better then netfabb.
Netfabb i use when i need to edit errors or to cut objects.

It is incredible how many models on thingiverse is faulty.
