This STEP file contains the base for a Filament-Cutter, which is being used for the SMuFF.
This base module allows you to create your own solution on hotends/extruders not covered by any of my models.
This base module is being used for the DDE-Orbiter, DDE-BIQU-H2 and the Ender-3 E3D-V6 models.
A live 3D view of this model can be found here.
The author hasn't provided the model origin yet.
