This is a bill-of-materials for a direct-drive, 3D-printable, reversible (right or left-hand filament release/clench) extruder mechanism. It is designed to work with the E3D V6 hotend, although other hotends with a similar neck style (e.g, Ubis) could be fit with a change to the Finix Extruder collar diameter and height. The Ubis collar is included as a bonus component.

1 Bonus collar files. The default (assumed) hot-end for the Visible Robot is the E3D, though others may be used.
2 Bonus mount files. These are available in the printable file download and also as design files, but not required as an integral component to the finix_extruder. The finix_extruder_platform is the component used to mount a single Finix Extruder to the Visible Robot or the Visible 3Bot.
