Adjustable tension

The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament. This gives you the power to adjust according to your preferences and to optimize for the type of material you are using.


To be able to do material changes in a snap, simply activate the Quick-Release lever to release the tension and pull the material to be changed out of the extruder, keep it activated and insert the new material.

More choice of materials

The hardened steel Dual Drive gears allow you to work with common and abrasive materials.

Community Sourced Design

This extruder design was proposed to Bondtech by Olof Ogland. It’s based on the thoroughly tested BMG (Bondtech Mini Geared) and adjusted to the Prusa Mini original design.
