Challenge of the week!

Hi everyone. Hope you are all having fun here!
Here is my challenge of the week. Anyone interested, feel free to jump in!

[TIG]

That's relatively easy!
Lots of repetitive shapes.
Make them as components, 1 per segment of a circle [say 24 ?], and arrange then around an axis as a radial array at 360 [Rotate+Ctrl /24 or the numbers needed].
I wouldn't try to punch every perforation unless you want true shadows to be cast.
Otherwise make a transparent png of each piece and apply it as a projected material onto the mesh faces in the components

Well, thanks for the advise, TIG.

Yes, originally I wanted to punch every perforation, and that's what make the challenge. I tried your method using png and projected the material. but everything is distorted after the curved.

The attached is what I've done so far. Far from what I wanted to achieve.
