Actually, after trimming the excess material top and bottom and stretching the fabric more… it is fiddley and I could certainly improve upon it, but I’m building my water cooler laptop GPU into my laptop bed stand and not primarily trying to make air filters. This is just a filter to go into a centrifugal fan based airbox, so I’m going with it for now. I’d rather spend time modeling and integrating some other stuff into the laptop stand like some studio monitor quality sound and better tabletop mounting brackets.
