Buy Dual Extruder

[websmr]

Hi

I have a i3 pro B acrylic and I'm thinking of buying another extruder but in the store of geeetech I'm not sure if I need to buy just another extruder or I need to buy the pack of two extruder because I see in the images, they are differents.

Single

Dual

In the image i see the're a little different, for example the heater is at a greater distance from the extruder in the single model than in the dual, which are closest to each other

I have basically the same question.
Can I buy a LEFT hand Geeetech extruder assembly to add to my Geeetech Prusa i3 A pro?

I've do this update last summer...
... I've just buy the left extruder, one spare feeder in order to change also the original MK8 to "black feeder versione".
But pay attention that you need also bracket to assembly the two extruder, dual extruder holder, stepper and maybe also power supply because the i3B original one is small...
