Prusa Mk2S with MMU 2.3 Hotend Upgrade
thingiverse
**Tested and Working!** I'm leaving this as a WIP pending feedback, but I am currently running this on my MK2S with MMU. Not intended for use with official Mk2.5 upgrade kit. Due to the PINDA placement modifications, this will not align to the build plate for mesh bed leveling. This is an extruder mod for the Prusa i3 Mk2S with MMU to allow use of the 40mm Noctua fans and the surround fan nozzle that comes with the new i3 Mk3. This replaces parts, "extruder-adaptor-mm" and "x-carriage", from the "Original Prusa Mk2S Multi Material" files found at: https://www.prusa3d.com/download-printable-parts-stl-mk2s-multimaterial. These is the red and blue parts (respectively) in the attached CAD images. This should be used with parts, "extruder-cover", "nozzle-fan", and "cable-holder" from the "Original Prusa i3 MK3" files found at: https://www.prusa3d.com/download-printable-parts-stl-mk3. Use your existing "y-splitter" part. These are shown as transparent or gray in the attached CAD images. This eliminates the need for the "Tilted Adapter for Noctua UPGRADE" and assumes you have a 40mm x 10mm fan for extruder cooling. **The 40mm x 20mm fan will prevent the limit switch from triggering - DO NOT USE.**
