Q*bext (Quick onboard extractor) - Fume extractor

thingiverse

This is a fume extractor for working on smd components and take away the fumes from welding. It has a long "nose" that permit to suck the vapours from the spot where you are working. It uses a 140mm high pressure fan (12v or 24v as you like, I power mine from the bench psu). You can tape a carbon filter in the exhaust of the fan (or use one of the filter holders you find here). I provided a nozzle to use for better capturing the fumes (but you can do without it and use it as is in the photo).
