Features:

  • A lightweight high-resolution extruder upgrade for the popular Prusa i3 MK3S and MK2.5S 3D printers with optimized design to use Mosquito and Mosquito Magnum hotends.
  • Upgrade your Prusa with a Bondtech Mini Geared extruder featuring higher gear ratio – 3:1 – that allows for extra push force and higher resolution.
  • Print Faster Or With Higher Quality: This lightweight extruder will allow your 3D printer to print faster or to achieve even better surface quality.
  • Reduce 3D Printing Issues: Decrease the risk of heat creep to avoid clogs and improve filament feeding by avoiding slipping and deformation that cause under and over extrusion issues.

Details: This is a Bondtech upgrade for the popular Prusa I3 MK3S+/MK3S and MK2.5S that will allow the use of the world acclaimed Mosquito hotends. This kit contains only the necessary parts to convert your current extruder to our own popular design based upon our BMG (Bondtech Mini Geared) extruder with 3:1 gearing ratio for better precision and resolution together with optimized geometry for the heatsink cooling and professional SLS 3D printed housing. This Upgrade Kit does not include the Bondtech drive gears (already supplied by Prusa). To use this Upgrade Kit, you will also need to buy the following: a Mosquito Hotend or a Mosquito Magnum Hotend for higher material flow; the Boron Nitride Paste; the SLS X-Carriage Kit for higher temperature and mechanical resistance (you can download the STLs in the Resources section and 3D print them)
