Prusa I3 MK2.5S / MK3S / MK3S+ Extruder upgrade
A lightweight high-resolution extruder upgrade for the popular Prusa I3 MK3S 3D printers, featuring an optimized design achieved with the help of the community.
This upgrade kit is compatible only with the original All Metal V6 hotend that is supplied with each Prusa.
Upgrade Your Extruder
Upgrade your extruder to a Bondtech Mini Geared with higher gear ratio – 3:1 – that allows for extra push force and higher resolution.
Print Faster Or With Higher Quality
Use a lightweight extruder that will allow your 3D printer to print faster or to achieve better surface quality.
Reduce 3D Printing Issues
Decrease the risk of heat creep to avoid clogs and improve filament feeding to avoid slipping and deformation that cause under and over extrusion issues. For even more effective HotEnd cooling we recommend a fan with high pressure like Sunon’s MF40100V1-1000U-G99 or similar.
