Topic: Air filter for SD2 or 3
this is designed to work with a charcoal inset filter i have not designed a spacific filter for this but i will later you will need an appropriate sized fan insert i have found there are usb adapters to run a 3-4 pin computer fan so i need one of those a fan of course and i will clarify my design later this is designed so i can attach a vent to the exterior of the case i may want to have 2 openings so that the heat is beign circuleted back into the case
so the hardware is a fan 4 screws and a charcoal filter
