Filter foam for my PC case?

[Box Brownie]

The foam filter element in my Lian Li case is 'shot' so wondering if anyone knows a source of small quantity of approx 3 to 5mm thick filter foam.......................or maybe a mesh type piece that would be suitable and could be made to fit???

TIA

Try a quick trip abroad on some photography fun trip and get duty free bottles encased in the mesh type foam. Win win as I see it.

I used these a couple of years ago. Maybe they have something that fits

Not as good as a trip abroad

Thanks for the replies & insights

I have since found this https://www.amazon.co.uk/dp/B01BO6P814/?coliid=ITCYQAADU30K0&colid=1QKPELU532RG&psc=0&ref_=lv_ov_lig_dp_it and though not the most budget worthy it will meet my needs for some time to come
