Hi all, Does anyone know where can I get a mesh sheet that is similar to the following images? (Don't need the indents) It feels like it's made of steel, because it's cold (unlike plastic) and hard (unlike aluminium) to touch. I thought it was wire mesh, but looking closely I think it's actually fine perforated sheet. It's hard to measure but I think they are 1mm holes with 1mm pitch? I have seen it used a lot in cases' ventilation, but have never been able to find a source to buy a sheet of it. It's for a case mod project. Thanks.
