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.
