Dual rocking extruder for Prusa i3.
Direct extrusion with a single stepper motor.
Basculating heads prevent inactive nozzle to interfere with the part already printed avoiding contamination.
Anti-oozing system.
Reduced mass allow direct extrusion.

In order to make the project more "readable" I tried to simplify and put in some order.
i) Eliminated the 3mm version (too hard to make it working!)
ii) Added 0.5mm clearance from heatsink to backplate, so modified Idlers, Idlers_pivot and Pendulum.
iii) Modified Idlers to avoid mutual interference and Servo_Cam interference
iv) Modified the fan duct (print fan) for a more efficient cooling
v) Added "mouse ears" to Pendulum and BackPlate to improove adesion and make prints easier ( if you don't want them you can do a "Divide ojects" and remove).
