Elegoo Centauri Carbon HEPA Filter/Muffler Extended

I wanted to muffle the sound for the aux fan intake. I replaced both auxiliary and case exhaust fans and that helped but wanted it quieter. So, I used Mongrel’s design and remixed it and came up with this simple idea and it works great. The intake doesn't need a filter so I removed the brace that holds them on the exhaust side. I didn't have round magnets so I changed them to what I had, but can be easy to put round ones with a minor change. I also made the intake hole larger for better airflow. With the printer on and no rear fans running it’s at 30 dBA with new fans 📷 Image redacted — claim this model to add your own media Just the case fan on it’s at 46 dBA without muffler With muffler it’s at 42.9 dBA 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media With both fans on it’s at 58.7 dBA without muffler With muffler it’s at 48.6 dBA 📷 Image redacted — claim this model to add your own media 📷 Image redacted — claim this model to add your own media As you can see, this muffler really helps in bringing the sound level down.
