3D model of a 120mm fan silencer for 3D printing (STL file)

Hi there. I’m looking to have an STL file of a fan silencer.
Let me explain:

I have several crypto miners, using extremely loud 120mm fans.

The fans are only intake – it’s not a push-pull config.

Bellow is a review of a silencer/muffler that would suit my need, but unfortunately, no public STL file is available online for it, and the seller is unresponsive.
I’m not asking you to make a similar model per say (you can if you want, as long as it works I really don’t care. If you can think of a better design, please follow your instinct).
The part I’m referring to is the round part in the front. Notice the mesh-like interior.

More pictures and further dimensions will be provided if needed.

Thank you!
