Silencer for 40x40mm fan (e.g.Noctua)
thingiverse
This radial silencer effectively reduces fan noise from 40x40mm fans. I've successfully applied one to my MKS Gen L case, significantly lowering the volume of the fan blowing into it. Unfortunately, it doesn't work as well with hotend fans. The silencer functions by reflecting sound waves emitted by the fan, essentially creating a sound maze that disperses noise without obstructing airflow. Its design ensures no airstream is blocked.
