Dual extruder for flex material

I made this extruder for flexible filament. the two bowden extruders that i have are not working with the flexible filament.

I brought one extruder down and one on the frame.
This saves weight on the carriage.

- 3x 30*30*10 fan (2 Optional for cooling the extruder motors)
