Once you use the vtkSTLReader, the problem becomes boolean operations
on a vtkPolyData, nothing to do with STL anymore. The first thing I
would do is read your file and then immediately write it with
vtkXMLPolyData writer and load that file in Paraview and see if it
looks reasonable.

Also, what do you mean "you have failed"? Are there compiler errors?
Run time errors? Incorrect results? etc.
