NZXT s340 Elite magnetic puck alternative?

Hey guys, I was wondering if anyone knew of a something like this:

it's the magnetic puck off of the NZXT S340. I love the idea of doing something with the front of my case. Mine couldn't be magnetic, I would have to glue it on but that's alright.

Tbh it just looks like a piece of plastic but I figured someone here might know of a similar object I could use.
