I am creating a homemade fume hood so that I can do soldering with less worry of having negative effects in the future on my health, currently I have made the fan model, which attaches to motors I have, but have not simulated air flow which I will do later. I still need to make the frame and the housing for this. (btw this fan is a large fan like one you would find in an air purifier or dehumidifier for your basement)
