What fabric to use as a fan grille?

[M76]

I'd like to replace the cover of my case with a fabric that let's trough airflow, but looks dark enough so as you can't see the insides of the case.

Is that even possible? I've experimented with speaker cloth, but it's no good, it completely blocks airflow.

Basically any mesh will do, it doesn't have to be fabric, it can be metallic or plastic for all I care. But it has to be black.

Most will block airflow. What you might need is depth. Then a crate like grill might let enough airflow in, yet still provide some of that darkness.

I was looking at some steel meshes online and they have some that claim to be 80-90% open, while the actual holes are very small. Wonder how would that affect airflow.

Canvas might work but you could get modder's mesh https://mnpctech.com/case-mods-gami...l-intake-front-fan-slotted-diamond-round-hex/

You can be some laser cut mesh screen on alibaba - heaps of designs and sheet thicknesses to choose from.

Alternatively just google "etch mesh" and do some up by painting your own.

I use well stretched tights.
Cheap, very effective and easy to replace.
