E3D v6 hot end holder (bowden)

thingiverse

The versatile and compact E3D v6 hotend assembly serves multiple purposes on a 3D printer. It can function either as a direct drive for direct extrusion of filament from the meltzone or serve as a Bowden tube, utilizing an air driven or mechanical tension system to feed filament through a lengthier path from a secondary source, which is commonly seen in delta printers and those requiring increased rigidity at lower print speeds.
