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.

This Upgrade Kit requires:

  • A Mosquito Hotend, or a Mosquito Magnum Hotend for higher material flow
  • X-Carriage Upgrade which can be printed. The STL files can be downloaded here
