Modular Fume Extractor 8cm Fan

thingiverse

This is a fume extractor. It's used to reduce the amount of fume being subjected to while soldering. I have used 2 x 8cm fans, one printed filter box, and a dish sponge. According to your needs, you can print more filter boxes and add more or fewer fans. It is successful in preventing you inhale the whole fume coming out from the soldering in one go, which can cause a lot of health issues. Of course, it's not a replacement for a proper fume extraction system, but can be an improvement in your soldering environment. Parts need are M3 bolts in different dimensions according to how you wanna place filter and fans. The filter inside is a sponge. I will replace or add one more filter box filled with a cheap carbon filter. Sponge is just to test it, but it improves soldering comfort just with dish sponge too.
