4 in 1 out multi filament upgrade M6

This is yet another 4-way splitter for multi color extrusion. I was not able to test it yet, but it feels very smooth when in push the filament with my hand.

This way i hope to reduce the friction of the filament in the splitter and have a smooth transition.
I used these "push-through" fittings:
