Had some of these turn up today. Just to try & filter/catch some dust before it gets sucked through the machine.
The 8cm is a nice size for the intake fan.
Thanks for sharing the tip @Matt
I had a moment to install the vent cover today, had no idea the mesh was that fine on them!
Also it’s overkill, since it’s already magnetic… I added neodymium magnets I had left over from a project. Turns out they fit nice for the corner holes, one less thing in the parts drawer of doom.
