PTFE Tube Extrusion Mount

thingiverse

A mount for securing the PTFE tube fitting to 2020 extrusion. With the other end attached to your direct drive extruder, this maintains a constant tension on the filament, rather than the print head tugging back and forth on the filament causing underextrusion. UPDATE: v4 adds a recess on the backside for another fitting to add a second, 1-2 in. long piece of teflon tube. Filament was binding up inside the block and causing failed prints. Also adds countersink for the M5x10 socket head cap screws it was designed for.
