(i have different fume extractor design that is smaller and a lot better looking http://www.thingiverse.com/thing:2202233) This fume extractor can be used with the hose attachment for larger jobs like desoldering components from a T.V. or a fume hood for everything else. Future parts might include a fume hood with helping hands, a cyclone for the hose so small pieces of plastic can suck up stuff with out hurling it at the fan blades, and a side body that can hold solder. The 1st side body can accommodate a rocker switch(14mmx19mm hole) and a potentiometer(a 3mm led also fits in the hole). My pot turned out to be broken so its not wired in there in the pictures posted. For a filter an active carbon pad can be used(https://www.amazon.com/Carbon-Filter-Activated-Weller-Absorber/dp/B009AE8DWO/ref=sr_1_2?ie=UTF8&qid=1466311145&sr=8-2&keywords=fume+extractor+filter), active carbon or charcoal pebbles(active carbon pebbles can be found at wal-mart in the fish aisle and work really well) but even without a filter it still helps because its pulling the fumes away from your face and disperses it up. fan size is 80mmx80mmx25mm. A ball bearing fan should be used instead of sleeve since it will be mounted horizontal.
Make sure your esteps and flow percentage are calibrated. The tolerance for the moving parts are >.15mm and non moving parts are 0 or .05mm. If you do have a tolerance problem please leave a comment so if several people have the same problem i can upload a different tolerance for a particular part
The video posted shows my fan wired up and working but it can be better because I didn't glue down any of the non-moving parts like the fan shaft to the main body. It can be little more airtight but still sucks up fumes no problem. If you use active carbon pebbles you will need a screen glued on the fan shaft top and fan cover. I used a used fabric softener for a screen but anything that air can pass through will work.
This was made in fusion 360 and there's a time-lapsed video below mainly for my youtube but still cool to see.
