Thingiverse
This is a plug meant to cover the entrance to the resonator inside the air box.I printed mine with PLA but anything should work really.Support is necessary. I had issues with tree supports and with normal support settings it should be easy to remove and print much faster.Note that support on the inside of the hollow cylinder area does not need to be removed.
