If you changed to Trinamic 2208 stepper motor driver and replaced the all noisy fans of Anycubic i3 Mega, only thing you can hear is the blower fan noise because nobody makes a quiet blower.
This upgrade will enable you to replace it with a silent Noctua or Ainex 40x10mm axial fan and cut down the noise to "zero" and makes your printer "ultra silent".
Included duct is a short design, so the axial fan works perfectly.
Hotend must be rotated 45 degree to clear the electrical wires.
Only parts-fan-bracket must be printed with a support enabled.
Remember to come back and post what you've printed as Make.
It's good for the designer and the community (that means you)!
