Solder Fume Extractor

🔧 Solder Fume Extractor (120mm Fan / USB-C / Optional Battery) This is a solder fume extractor I built to help reduce fumes while soldering, keeping the workspace air a bit cleaner. I didn't find any Fume Extractors that fit everything I wanted, so when designing this, I had a few goals in mind: Use a standard 120mm PC fan Include a replaceable filter Be powered by USB-C Optionally be battery-powered for portability I designed two power configurations: One that achieves all of those goals and another for people who don't want to deal with the battery part and would rather just plug in a USB-C cord and be done. (mounting holes are built in for both) 🔋 12V UPS Version (Battery + USB-C) This version uses a 12V UPS board with two 18650 batteries, allowing it to output a constant 12V even when unplugged. It charges via USB-C, making it fully portable. 🔌 USB-C Trigger Board Version (Plug-and-Play) This version uses a USB-C PD trigger board to power the fan directly. No batteries required—
