The T04 version solves the difficulty found to load the filament through the first vertical curve.

I needed to reduce the space needed by the gravity's clip in the front part, so I have remixed the clip so the PTFE tube can come from up to down. The space needed has been considerably reduced.

The diameter of the hole for the PTFE is 4.5mm. I have tested it with differents diameters but the best approach for me was 4.5mm.

Also, I have tested with PTFE of different sizes successfully --> 4OD-2ID, 4OD-3ID and 4OD-1.9ID
