#description This is a simple air filter. It filters the air with a single paper towel and a 80mm fan to push the air through. the paper towel should catch a lot of the regular indoor dust and spores from the air. #construction 1. find a 80mm fan 2. print body. (note that the design is quite tight) 3. fit fan on the bottom and add a 12v jack 4. wrap paper towel on "filter holder" and introduce into filter body, the holder should keep it in place 5. put lid on and use #work to do 1. redesign filter holder as its really fragile 2. design feet, it currently uses some sticks
