DIN Rail Stand (regular & deep)

This stand for 35mm DIN rails comes in two versions: one for the regular and one for deep din rails (7.5mm or 15mm deep).

It is a remix of the [DIN Rail Stand by RedWraith](http://www.thingiverse.com/thing:2068383). I modified his OpenSCAD file to get rid of the DXF import by drawing the contour as polygon directly in OpenSCAD. In addition, I added the version for the regular 7.5mm deep din rails.
