I've posted a feature request on the netgen SF page and just added it here for interested people.

Add the possibility to use the assigned boundary conditions to add name for STL solids.

This way it can be used in SnappyHexMesh in OpenFOAM without having to split the STL file in seperate geometries and will allow for a fully defined surface without leaks.

example of ACSII STL file as it is now when exporting, only one triangle

Code:
solid
facet normal -0.9990862153 -0.03061211299 -0.02982671458
outer loop
vertex -4990.620641 -306.11373 0
vertex -5000 3.061616998e-13 8.333027861e-09
vertex -4991.095326 0 -298.2741069
endloop
endfacet
endsolid
wanted export from NG when one have assigned the BC's

Code:
solid Boundary_0
facet normal -0.9990862153 -0.03061211299 -0.02982671458
outer loop
vertex -4990.620641 -306.11373 0
vertex -5000 3.061616998e-13 8.333027861e-09
vertex -4991.095326 0 -298.2741069
endloop
endfacet
endsolid Boundary_0
