120mm fan filter mesh
thingiverse
Remixing the original larger hole version because the original was only 1mm high making it very flimsy. The holes didn't match up with any of the 120mm fans I had. Also the mesh was just lines over each other, it wasn't a real mesh. This is 3mm, the mesh is an actual mesh, the holes match 120mm fans, and I added some numbers next to the holes for identifying the holes. For anyone wondering as I did, despite being a very dense mesh, air passes through easily, so don't worry about this reducing your 120mm fan's airflow.
