Anycubic i3 Mega filament pipe (guide)

This is the filament pipe to be installed between the filament feeder and the magnetic filament sensor. Normally if the sensor is stiff and the filament bobbin is located very close to the printer, the filament doesn't get through without an effort. This causes clicking sounds from the magnetic lock of the sensor and sometimes the sensor gets even disconnected from the magnetic lock and gets very close to the feeder (which is not nice). The filament pipe solves this problem nicely.
