Filament guide for 20mm rails (PTFE insert + M4 T-nuts)

thingiverse

After moving the flying extruder of my TLM and converting it to a Bowden setup I needed a filament guide for the new location. So I quickly drew up a design in Fusion360. It's designed for the 20mm spacing of the rails. One screw is sufficient (due to my wiring). The tubing I use is Capricorn XS. 700 mm length is sufficient for my TLM with the top of the extruder bracket at 515 mm height above the bottom main plate.
