Another MK5 Dual Extruder

This is about my supervisor's idea, now we had a DC motor for MK5 extruder, and we are waiting for the mk6 nema 17 motor, so in awhile, we want to try it on our DC motor and see how it work and we can use it later.

Like the original extruder filament drive files of Jag http://www.thingiverse.com/thing:7113 , i want to move the motor's screwposts so we can insert the DC motor on.
