Anycubic I3 Mega Silent Extruder Lever

This lever eliminates the annoying loud "click" noise coming from the extruder unit. Simply insert a short 4mm dia. PTFE teflon tube into the hole, and ensure printing position is identical to the image above. Have you ever wondered where the clicking noise originates? There are numerous false claims about what causes the "click", such as: the extruder motor lacks sufficient torque; or the extruder gear slips. However, none of these explanations are accurate. The real cause is this: the original metal extruder lever wobbles slightly even when the screw is tight and it collides with the metal mounting bracket at high speed creating the loud "click". This typically occurs more frequently during filament retraction.
