This didn't work on my Ender 3. The gears got blocked by the extension to the tube holder, causing the filament to not extrude.

You have to cut the PTFE inlet with a cutter like the rest of the shape.

Hi, how is this different from the original? tighter tolerances?

If so, I will definitely try it out!

The PTFE-Tube input goes closer to the gears. On this way, flexible filament does not longer squeeze and clog at this position.
