This is the Sherpa Mini Extruder, a ground up design developed by Anlin and the team at Annex Engineering. It's a dual geared hobbed filament extruder designed for use with any printer. It features a 50:10 or a 50:8 gear driven design to provide torque while being able to be near silent. You must perform your own tuning to get the best results.
