Bambu Labs 4-in-1 popular hub is a great junction for all filament feeds. It has a unique mounting point which I have fitted to my Mount. Great care has been taken to ensure the angles are correct so there is little to no deflection of the filament through the pathway as it enters the Printer.
It is an easy install which allows you to remove the top coupling. Two m3x16 screws attach the Mounting to the Back panel and one M4x12 to fit the 4-in-1. Ensure your PTFE are cut square and fresh for the installation to avoid any catching points.
** This tool will come in handy for working with the PTFE.
