thingiverse

Another fan silencer. This should be compatible with Ender 3 / Ender 3 Pro / Neptune 2 or any number of clones. This was inspired by the excellent work done by SvenKielmann https://www.thingiverse.com/thing:3612639 This silencer should provide for better airflow. The design optimizes the baffle area leading to the rear exhaust. * Fan_Silencer_10.stl - 15mm height * Fan_Silencer_10_mirror.stl - Mirrored model for Ender 3 Pro, MeanWell --- The Decibel Ranking of my Fan Silencers are as follows (lower score is better).

The cellphone was placed on top of the PSU with the microphone facing the side of the exhaust fan.
