Now you can upgrade your Original Prusa Mk2.5/Mk2.5S to use the new Mk3S+ extruder. This part adds an actuator for the X-axis end-stop which is missing from the Mk3-style extruders. The actuator also includes a fan cover similar to [thing:3624919](https://www.thingiverse.com/thing:3624919) You will need a 25mm M3 bolt (bottom position) and one 16mm or 18mm bolt (upper position) to hold the part in place. Other than this, you'll need to do the Prusa Mk3S+ extruder conversion: - [Mk3S+ extruder parts](https://www.prusa3d.com/prusa-i3-printable-parts/) - [Optional: Improved part cooling fan duct](https://www.thingiverse.com/thing:4588226) - [42.3mm PTFE liner](https://shop.prusa3d.com/en/mk3mk3smk3s/1441-hotend-ptfe-tube-mk3s-mmu2s.html) (you can trim your old one if it is in good shape) - [Assembly instructions](https://help.prusa3d.com/en/guide/3b-mk3s-extruder-upgrade_186842) - [Upgrades from Mk2/Mk2S/Mk2.5] will also need [IR filament sensor parts](https://tinyurl.com/2wnm63bn) and may need [the white wire in the cable re-pinned from the Mk3 pinout to the Mk2.5 pinout](https://tinyurl.com/vsnjb5k7))
