Upgraded extruder for MK3S+ with MMU3

I designed this mod for my beloved MK3S+ & MMU3 combo after I tried every available „chimney” and extruder mod for this printer. Although I really liked my setup, the structure of the extruder and chimney made the color-changing unreliable compared to the competitors.

The main feature is the modified idler which rotates around a different axle, and the inverted chimney. This two combined make the system more robust and much more reliable. 

The assembly has the following upgraded parts:
- Idler
- Motor Plate
- Extruder Body
- Chimney
- Chimney Base
You will need the following extra parts from you MK3S+ spare bag (9. bag):
- M3x6 screw (1x, from MMU3 leftover parts)
- M3x10 screw (2x)
- M3x12 screw (1x)
- M3 nut (1x)

You will not need any additional parts.

The assembly is fairly easy, nearly the same as the original one, all differences are listend in the attached document. If you have any questions please leave a comment:)
