I got a problem on Slicing, there is a Bridging Layer in the middle of the part who shouldn't be there and varies with the rotation.
I tried to fix the part with netfabb, same result.
Change the layer height to 0.2001 and all will be okay.
This is a known and strange thing with S3D. There's an issue with the shape that confuses the slicer when the "issue" align exactly with a slice boundary. By changing the layer thickness by a very small amount, the "issue" no longer falls at a layer boundary....and the part slices correctly.
