Following along the lines of our 4th Generation Micro Extruder designs for the Kossel Mini and Kossel XL here is our Flex3Drive for Turnigy Fabrikator. Coming in at under 31 grammes, this extruder is as small as they get, for one of the most compact 3D printers on the market. Suitable for 3mm or 1.75mm filament.

This little beauty fits onto the small ledge bracket that holds the hotend in place, and allows you to remove the direct drive extruder components, its spring loaded tensioner, and the E axis motor motor off the carriage, reducing your moving mass by around 450grammes (thats almost half a kilogram!). Aloow your Fabrikator to print faster, smoother and improve the print quality. Print at layer heights you couldnt achieve before, thick and thin.

The fundamental difference compared to the Kossel Mini version (aside from the end effector) is the use of a vertcially aligned tensioner. Whilst this tensioner is another version of our rigid two bar tensioner design, it incorporates a combined adjusting screw so no only does it give the quick release and easy access for filament loading and unloading, the degree of tension it applies can also be adjusted.
