Original Prusa i3 MK3/S to MK3S+ upgrade kit

Upgrade kit for the Original Prusa i3 MK3/S to Original Prusa i3 MK3S+. With this upgrade, we are introducing the SuperPINDA and a number of small changes. X and Y axes have slightly improved plastic parts and u-bolts were changed to metal clips which are easier to mount. A number of minor changes were done to the extruder plastic parts to improve overall reliability.

You will need this upgrade in case you are using MK3 and planning to buy the MMU2S.

Otherwise, if your MK3/S runs without any issues, you will not gain any significant printing quality improvements.

This product is supplied as a kit - you must assemble it by yourself!

Printed parts are NOT included! Please print them before you disassemble your MK3/S! (Filament is included in the upgrade package, STL files and assembly instructions are available below)

Completely unimpressed that they put the fact that no printed parts are included after all the other product info. You won’t see it till you scroll on a phone, even a PC. One star because that’s deceptive and it makes no sense that they don’t offer an option to buy the printer parts.

A great kit ruined by Prusa cheating their loyal fans. Prusa has changed. Customers used to be the focus. The absence of the printed parts at this price is ridiculous, to not offer them at an additional price is outrageous. Hey Prusa, Printers aren’t always working and when that happens, it’s a good time to upgrade! Thanks for making this harder. I am really disappointed with Prusa.

The set may be good. But note with the order The company sends the cheapest possible option (despite the selected other) . And you know how packages are treated in the collective transport of the post office :)....
