Prusa I3 MK2.5S / MK3S Extruder upgrade


This extruder upgrade kit is for the Prusa MK2.5S or the Prusa MK3S where you already have our Bondtech gears. This kit contains the necessary parts to convert to our freshly designed extruder that uses 3:1 gearing ratio for improved precision and resolution, optimized geometry for the heat-sink cooling and many other improved features. It also reduces the moving weight to reduce vibrations and ghosting.
