Smooth and silent filament tube guide for Anycubic i3 Mega

This is a smooth and 100% silent filament feed guide for your Anycubic i3 Mega.

Due to the slight curvature of the hole for the filament tube, the filament retains its "natural" curvature and is not guided too tightly or forced in an unfavourable direction. The tube flexibly adapts to the forward and backward movements of the extruder and the degree of bending of the filament (see video below).
