E3D-v6 hot ends are supposed to have room to let bowden tubing go all the way down to the heat brake even when using a direct drive.
One modification idea I have is to open up the bottom of the direct drive extruder so bowden tubing can be pushed inside. This channel would go all the way up, but the plastic that guides the filament would still be there both to guide the filament and hold the bowden tubing in place.
Then a piece of bowden tubing could be cut to fit the entire E3D-v6 hot end and the extruder and fitted in when assembling.
In theory this would allow the extruder to push flexible filament directly into the tube and all the way down into the hot end giving flexible filaments minimal resistance all the way down to the nozzle.
I'm planning on using an E3D-v6 hot end when I build my Wilson TS in a couple of months. If no-one wants to experiment with this then, I'll probably try it.
