All parts required to convert your existing Original Prusa MMU3 (for MK4S or CORE One / CORE One+) into the Original Prusa MMU3 for CORE One L.
This set includes everything needed to upgrade your current MMU3 unit to be compatible with the CORE One L.
There are two available conversion options:
Lite version - without enclosure
Enclosed version - with top cover
Please note that some components are not suitable for 3D printing. STEP or DXF files are provided for these parts to enable alternative manufacturing methods.
Before you begin printing, carefully read the included instructions. Additional hardware components are required for the conversion and must be sourced separately.

Print settings: 0.20mm BALANCED
