Air Vent Diffuser

!!!!FAN ON BITAXE ASIC HEATSINK MUST BE BLOWING AWAY FROM HEATSINK, PUSHING AIR OUT!!!!Needs an extra fan on the bottom. I have a full on air filter below it, thus why the original is open base. Added STLs for 40x40x10 mm and 40x40x20 mm fans. Those are a little less optimized due to a barrier to the side where the air escapes, it has been revisiones in the open case one. You can edit the main one to turn it into the needed fan size.
