I really liked DJG3's Filament Sensor Funnel remix of Surfalex2000's Filament insertion guide as a way aid in directly feeding TPU filament but I did not have any PC4-M6 fittings for the back end for my PTFE tubing. But I did have some Prusa Festo M5-4 fittings that I had bought as eventual possible replacement parts that I could use instead.
I changed the screw threads to fit M5 fittings. After printing it in PETG, I used piano wire to clean out the hole so the filament would got in smoothly.
Hardware and Materials:
(3) or (6) Festo M5-4 fittings
