Prusa i3 Mk3 extruder base and cover for the MK2(S) multi-material

thingiverse

ATTENTION! The carriage-back will definitely collide with the extruder brackets on top. The maximum height is restricted to 190-195mm due to default bracket limitations. https://www.facebook.com/photo.php?fbid=1823209807743196&set=gm.917326815118467&type=3&theater Preview below: ============================ Extruder Body of the MK3 for the MK2 MMU This part ensures the extruder fits perfectly with the Noctua fan included in the future MK2.5 upgrade and the new fan nozzle from the MK3. The original MK3 has different hotend and Pinda positions, so I designed the carriage and base to eliminate hotend offset and reversed the Pinda holder clamp mechanism. The carriage and base are thinner on both facing surfaces when assembled. To use this modification, you need the MK3-x-carriage front and back. The front part (included here) has been modified: * Extension added to trigger the endstop * Small cutout at the edge for the fan due to nozzle position explained above My version of the carriage-back part is similar but with different filament sensor cable cutouts. Get other parts (fan nozzle, cover) from the Prusa website or GitHub page. 2018-03-31 Update: I took the current "R2" x-carriage (with the new belt mount) and added the same modifications of C1 to a new C2.
