Upgrade kit for Prusa Mini
High-resolution Bondtech extruder upgrade for the Prusa Mini with dual drive technology.

Update your Prusa Mini
Upgrade your Prusa Mini with a Bondtech Dual Drive extruder that fits seamlessly into the original setup.

Hardened drive wheels
Allows the use of abrasive materials that would otherwise wear the gears of your original feeder.

Print faster or with higher quality
With this Bowden extruder, your 3D printer can print faster or achieve an even better surface quality.

Adjustable tension
The knurled screw tensioner allows the user to fine-tune the pressure exerted by the drive wheels on the filament. This gives you the opportunity to adapt to your preferences and optimise for the type of material used.

Quick change
In order to be able to change the material in a jiffy, simply activate the quick-release lever to release the tension and pull the material to be changed out of the extruder, leave it activated and insert the new material.

More choice of materials
With the dual drive gears made of hardened steel, you can work with common and abrasive materials.
