Sherpa or TBGS extruder Direct drive conversion for Prusa mini V2
Dedicated to those who can't stand the prusamini bowden system, or those who want to print flexible filament.
Compared with the previous version, this version lowers the height of the center of gravity and shortens the length of the filament path by 4.5MM.
Since the TBGS extruder has the same pattern as the sherpa-mini extruder and has a similar shape, it can be directly replaced in most cases. You can enjoy the benefits of big gears.
