3D printed Soldering Fume extractor

thingiverse

This is an air purifier for electronics enthusiasts. The case contains a standard 12-volt DC fan and a compartment for a power adapter. The case is designed to accommodate a generic Aliexpress 40x90mm 12V 1A transformer module. All parts can be printed without supports, but the back panel requires gluing after printing. There's an opening for installing a potentiometer if you want to adjust fan speed manually. The top lid snaps into place and comes off easily to swap out the filter. Purchase a charcoal air filter designed for kitchen hoods at your local hardware store or online. Cut it down to 240x120mm, fold it in half, and insert it into the rear housing.
