Fume extractor

thingiverse

I have developed an innovative fume extractor design that is smaller, sleeker, and more effective http://www.thingiverse.com/thing:2202233. This versatile device can be used in conjunction with a hose attachment for large-scale projects such as desoldering components from electronic devices like TVs or computers, or as a standalone unit for everyday tasks. Future enhancements may include the addition of a fume hood with built-in helping hands, a cyclone attachment to capture small particles without clogging the fan blades, and a detachable side body that can store solder. The initial prototype features a rocker switch and potentiometer, but my potentiometer was faulty during testing, so it's not wired into the design. To filter the fumes, you can use an active carbon pad (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), or charcoal pebbles, which can be found in the fish aisle at Walmart. Even without a filter, this extractor is effective because it pulls fumes away from your face and disperses them upwards. The fan measures 80mm x 80mm x 25mm and should use a ball-bearing fan instead of a sleeve-bearing one to ensure smooth operation when mounted horizontally. Print Settings: Printer Brand: LulzBot Printer: TAZ 5 Rafts: Doesn't Matter Supports: Yes Resolution: .3mm Infill: 20% Notes: Make sure your printer's esteps and flow percentage are calibrated. The tolerance for the moving parts is >.15mm, while non-moving parts should have a tolerance of 0 or .05mm. If you experience any issues with tolerances, please leave a comment so I can update the design accordingly. Post-Printing: The video demonstrates my fan in action, but it can be improved by gluing down the non-moving parts, such as the fan shaft to the main body, for better airtightness. With active carbon pebbles, you'll need to attach a screen to the fan shaft and cover with a piece of fabric or another breathable material. How I Designed This: I created this design using Fusion 360, and there's a time-lapse video below showcasing the process.
