Ordbot Hadron dual extruder mount

Dual extruder mount for the ordbot hadron.
The uploaded stl files uses M4 bolts to screw it down to the carrige, the ordbot comes with holes for M3 so either you need to drill out the holes or change in the open scad file to use M3 bolts instead.
The nema 17 motors have a depth of 40 mm. If you want to use other motors it is possible to configure this in the scad file.
Made to be used together with a minimalistic direct drive extruder solution like http://www.thingiverse.com/thing:15718.
