Original Prusa i3 MK2/S to MK2.5S upgrade kit

But if you want the full MK3S upgrade anyway, no problem! You can find it here.

Worth every cent!

The PEI sheet on my Mk2s was starting to show signs of wear, so I went with the Mk2.5 upgrade package instead of just getting a new PEI sheet. Worth every cent! The upgrade process went along without issues, and it took me about 3 hours and 3 cups of coffee to complete. The Noctua hotend fan makes it quieter, the flexible bed makes it easy to get prints off and the new X-axis parts bump up print quality and thermals compared to the stock Mk2s hotend.

Best Upgrade I have done so far.

I bought this upgrade so I can use the MMU2.0, but so happy with the upgrades, from the powdered coated spring sheet to the optical filament sensor. Not sure which parts made it run quieter, but it is. Prints are coming out smooth and better looking than before. Documentation was great and the added comments from others is a nice touch. Just remember to print your new parts first! Time well invested on my printer. Only had to back track once on some wiring I routed wrong, I recommend this for anyone with a Mk2s.
