Vertex-H with Single E3D-v6 Hot-end

This is remix of my Vertex-H printer published here.

The goal was to design lighter cartridge with single hot-end and to improve filament cooling air flow.

Both fans used in this design are 30x30x10mm. They are included in E3D-v6 kit.

This design allows to use the original PCB from Velleman, however you may need to replace the resistor to make sure E3D fan gets not more than 12V.

I am including 3 versions of e3d_clip THING. One is simply fixing E3D in place. e3d_clip_fan addresse
