Prusa i3 Mk2s MMU Modified Extruder For Bowden Style Input

I didn't like the feed input to the extruder, and if you have the spools above the printer, the filament can rub the extruder, and in my case make a squeaking noise that was annoying.

But this is also part of a frame support for 4 filament rolls, and i was using the 4mm OD PTFE tube. but i felt that some people might want just the extruder to fit in with their setup

2 modified Extruders
4 M5 x 7mm Brass inserts
