had this idea a long time, wanted to add dual extrusion to my Kossel, didn't find anythign that fit for me.
made some iterations with different push-fit connectors which all didn't work for me, so I thought the original E3D connectors may work, and they did.http://e3d-online.com/E3D-v6/Spares/Embedded-Bowden-Couplings-For-Metal-1.75mm-Filament
I used this http://www.thingiverse.com/thing:275593 extruder
I had to crank up the extruder acceleration quite a bit, it's just try and error until it works.
For GCODE generation I use S3D with this Tool-Change Script:
T[old_tool]
G1 X0 Y-70 F5000
G92 E0
G1 E-20 F12000 ; retract fast
G1 E-34 F1500 ; retract slow to prevent stringing
G1 E-150.000 F12000 ; reatrac fully fast to rip of eventual strings
T[new_tool]
G92 E0
G1 E151.000 F900 ; prime extruder
G92 E0
