It is a pretty straight-forward install, even if it requires you to disassemble the whole printhead :-)

@DeathMachine: The way i use it (as separate feeder lines, where i always unscrew the unused nozzle, not as a dual extrusion setup) it works pretty well, i have to change esteps every time i switch between 1.75 and 2.85mm filament tough.
How well did this work?
@reibuehl: I use a modified version of IRobertI's Alternative Feeder V2: https://www.youmagine.com/designs/alternative-feeder-1-75mm-version
Which feeder did you use for the 1.75mm side?
