Solder fume extractor with magnetic assembly
Description
I solder electronic components and wires from time to time and I was told solder fumes are rather toxic. I did not want to invest a lot since it's only a casual hobby for me. There are a lot of fume extractors here but I wanted to design my own version since it is also a way for me to develop my skills with Fusion 360. And I also wanted to use what was present in my closets, ie a 5v USB fan and a bunch of 5mm magnets I got from a previous project. The cool feature I designed is the way the parts attach to each other: they snap thanks to small round magnets and that makes changing the filter a very easy task. A video of the snap-on magnetic system: https://youtu.be/Gog3wz5vRpU You can choose to build it with only one carbon-based filter in front of the sucking side of the fan; or upgrade it and add a second filter, attached in front of the opposite blowing side. The main frame can be used for both versions so you can decide later if you want to add the second filter. Adding the second filter improves the filtration of course, but also reduces the sucking power (meaning you should do your soldering closer to the extractor). So I ended up with this design that I find very satisfying and useful (it works!) My USB fan comes with a metallic grid I re-used to beautifully finalize the design with its own screws (the model I used is referenced below). Components list: * one '80x80x25mm' USB fan (see model below) * 16 '5x1.5mm' magnets if you want a one-sided version (32 if you want the double-sided version) - available on Amazon, see below * PLA of course * one or two square piece of 80mm wide, 5mm thick carbon filter (cut it from a furnace or air purifier sheet) * CA glue to attach the magnets to the frames The fan I used: https://www.amazon.fr/gp/product/B06XRCDZDH 5mm magnets: https://www.amazon.fr/gp/product/B00TACFNXS A video of the working extractor in action: https://youtu.be/yA7RCwI52VQ
