Original Prusa i3 MK3/S to MK3S+ upgrade kit

The Original Prusa i3 MK3/S to MK3S+ Upgrade Kit is an official enhancement package designed to bring your MK3 or MK3S printer up to MK3S+ standards. It includes essential mechanical and sensor improvements that enhance print quality, ease of maintenance, and future compatibility with upgrades like the Multi Material Upgrade 2S (MMU2S).
This upgrade introduces the SuperPINDA sensor, which offers more consistent first-layer calibration unaffected by temperature changes. The IR filament sensor has also been refined for better filament detection. Additionally, the kit includes metal bearing clips for easier handling of Y-axis bearings and eliminates the need for U-bolts.

Key Features:

1. SuperPINDA Sensor – Provides highly consistent first-layer calibration regardless of temperature.
2. IR Filament Sensor – Enhanced detection for smoother operation and reliability.
3. Metal Bearing Clips – Replaces U-bolts, improving assembly and maintenance of Y-axis bearings.
4. Updated Hotend PTFE Tubes – New standard for better extrusion and hotend reliability.
5. Improved Extruder Design – Minor mechanical updates for overall durability.
6. Includes PETG Filament – 300g spool included for printing required plastic parts.
