Prusa Mk2.5S -> Mk2.5S+ Upgrade [X-axis end-stop actuator & fan cover]

Now you can easily upgrade your Original Prusa Mk2.5/Mk2.5S to use the new Mk3S+ extruder.

This part replaces “endstop-block.stl” from the official Prusa3D parts github with an X-axis end-stop switch actuator built into a fan cover. The fan cover portion is similar to thing:3624919 .

You will need one 25mm M3 bolt (lower position) and one 16mm or 18mm bolt (upper position) to hold the part in place. Other than this, you'll need to do the extruder conversion as you would when upgrading from a MK3S→Mk3S+ upgrade:

- Extruder parts (ignore the "endstop-block.stl part) - 42.3mm PTFE liner (you can trim your old liner if it is in good shape) - Upgrades from Mk2/Mk2S/Mk2.5 will need IR filament sensor parts and may need the white wire in the cable re-pinned ) - Recommended: Improved part cooling fan duct - Prusa Mk2.5S+ guidance Forum discussion link
