Has anyone use the Lucas Extruder on an i3v that is on thingiverse? http://www.thingiverse.com/thing:428312
There is not an x-carriage in his design for the i3v, but looks like the mod to the x-carriage would be fairly easy, since this design does not need a shelf for the extruder.

Since I am fairly new to 3d printing, I am still only interested in a single extruder on my printer & not a dual.
