Light Switch 13870519 for BMW vehicles V2

All credit to Anjoze, literally the same file as version 2 file of "Light Switch 13870519 for BMW vehicles by anjoze", the only change is that I cleaned up the model internals.

I noticed when i tried to print in Cura 3.03 it would fill the entire inside of the model for some reason. So I opened the model in Blender3D and noticed the normals on the bottom faces were facing in the wrong direction, so I corrected those. I also faces that were used in the model inner diameters and beveled "gear"
