You need a high resolution image of a thin piece which has holes. You can draw it as a vector, but that's said already in an earlier answer, so I try something else.
This is a photo of a commonly used piece of not so organic material. It had white background and unfortunately only low resolution - good enough for webshop. I lifted the width to 2000px with Smilla Enlargener (it doesn't make borders blurry, freeware) and erased the white background:
All surface details are useless. They vanish by changing all pixels to 50% grey with Curves:
Layer spare is a copy of the original.
The well machined geometric form probably is not wanted. It vanishes by applying Edit > Transform > Warp or Puppet warp and Distortion effects:
Warp is easy, but Photoshop's distortion effects are difficult to control. I inserted a slight Pond ripple. It created a couple of holes and blurry edges which had to be fixed manually.
Illustrator's Envelope Distort with Mesh would give more freedom. It works well also with photos. Transparent background stay in Illustrator if one opens a photo file. Pasting directly to Illustrator removes the transparency. See NOTE1!
Some 3D light and color are useful. I used Photoshop's Layer styles as a shortcut. Manual painting would give full control, but Layer styles are easy. This is Bevel&Emboss:
Layer style Color Overlay made it blue. In the next image a black background is added and the image has got perspective distortion (Edit > Transform > Perspective and Scale)
NOTE1: Instead of using a photo of cylinder head gasket or other object which has holes one can as well make a selection, fill it and make holes by making more selections and deleting. If the selection forms are drawn irregular from the start no warping nor distortion are needed.
One can get smooth selection edges with Select > Refine Edge > Smooth. Apply no feathering, the edges must have high contrast. You can always make them less sharp later if you find it useful.
ADD: If you want a pattern which can be used to fill areas you can start differently. Here's a 100x100 pixels image which is filled with yellow and freeform black shapes are drawn with a pencil. The idea was to have one big black block and a few smaller ones:
The edge zones are about 50% thinner than the yellow areas between the black blocks.
The image was selected, defined to be a pattern (Edit > Define Pattern) and a bigger rectangle was filled with it by using the Pattern Stamp:
That's too regularly repeating pattern when compared to your examples. But it can be distorted with Filter > Distort > Waves:
To test how it works the result is mapped with 2 a little different scalings onto donuts in a CAD program:
Just to show the difference here's one donut with the regular pattern which is not distorted One can see at a glance it's repeating.
