STL Filter - 3D Print Check

A new 3D Print Check option has been added when exporting an STL file. This tool checks a part for the following common topological errors such as:

1. non manifold edges
2. duplicate facets
3. collapsed facets
4. consistent normal orientation
5. open edges
6. shells

The tool also displays geometry information such as extents, number of facets/vertices, area, and volume. When saving an STL file, the user is given the option of performing a print check on the 3D model:

After saving the file, A dialog will appear for each object giving general information of the object as well as result of 3D print tests. Please find the attached reference images.
