i3V Dual Flexy/bowden

Should be noted that while this technically works... I abandoned the project a few months ago for the IttybittyDual extruder by Clough42.

Dual extruder. Prusa i3V 12". Half remixed Lulzbot flexystruder for 1.75 filament. Half Bowden. E3D V6.

10-15-15 added a new version with a rear mounted servo. This allows more room for print fans. I also added a fan mount that hold two 50mm radial blowers.
