I designed this piece because the original fitting stopped the discharge of the filament, it also happened to me with the Y-Splitters. Quick plug fittings bite the ptfe and degrade it quickly.

With the ECAS04 this does not happen, I mounted it in the middle of 3 days printing and the filament discharge did not fail again.

Print settings:

0.16 layer height.

Material: PLA or other doesn't matter.

With supports at the bottom for better quality.
