I designed this fan silencer for the Elegoo Centauri Carbon (should also work for the CC2) from scratch. It uses venturis to reduce airflow noise and minimize reduction of flow to/from the fans. It mounts using five 10 mm x 3 mm magnets and two alignment features. The alignment pin and hole use a screw and hole on the back of the printer to make sure it's aligned correctly and doesn't move around (see marked up pic). Share your builds and noise/dB reduction results in the comments!
I printed with 10% infill, supports enabled, and no brim. It can be printed on one build plate. The supports were somewhat difficult to remove, so share in the comments if you find better settings than the standard ones. My print had a good friction fit between the two halves, so I didn't glue them together.
