Designed to allow easier filament adjustments when loading/trouble-shooting MMU issues. Can join a short length of PTFE to a longer length (that feeds into a filament buffer for example). The two parts screw together/apart and save wear and tear on the PFTE tube when compared to using the PC4-M6 connectors to remove the tubes.

Made this due to starting to mess up the ends of my PTFE tubes having to disconnect them from the MMU2s (new to using it) for feed issues. Now I can just unscrew this connector to fix or do a filament change (new feed). Saw other versions but none that I though would work with a filament buffer.

The inside is curved to allow easy filament feeding into either end.

Print both (a) and (b). You will also need two PC4-M6 connectors per.

I printed at 0.1 but you might want to print at 0.15 or even 0.2.
