DIY Solder Fume Extractor

I was tired of breathing in solder fumes- especially when soldering lots, and lots of connections for the various multi-rotors I've been working on. I didn't want to pay the $50 or whatever ready made fume extractors have been selling for, so I repurposed a 12v computer fan, 12v wall-wart and a new-work steel duplex box I had laying around.

I tried using some carbon foam filter left over from an old window AC unit, but it restricted the airflow too much. I mostly just wanted to suck the solder fumes down and away from my face when I'm soldering, so even without a filter it works great for this purpose. The computer fan is also very nice- almost totally silent and moves plenty of air.
