Has anyone ran a much smaller extruder setup on a Prusa? (I assume that would be needed to run dual extruders)
Something like this?



I would think this would be a much better setup for several reasons.
Less bulk and weight to be moved around and supported.
Less parts to go bad, eliminating 2 plastic gears.

Seems there would be more torque on the motor since its not using gearing, is there any other disadvantages?
I would love to have a setup like that on the Prusa. Looks like an easier to maintain setup to me.
