If you are an electronics hobbyist, soldering is essential in almost all of your project, but the smoke/fumes from burnt solder and flux isnt something you want to breathe. It smells bad and can be very dangerous to your health but you can reduce the hazards by employing a fume extractor. Even if you only solder things once in a while, it’s a good idea to have a solder fume extractor to suck in those toxic fumes.
If you want to buy a good fume extractor from the market, you have to pay more than $70. So I have made my own by using a 120mm PC cooling fan and 3D printed enclosure.
I got the inspiration from the amazing 3D printed model designed by rdmmkr. I customized the model in Autodesk Fusion 360 to fit into my own requirement. I have used a 120 x 25 mm fan whereas the original design is suitable for an 80 x 38 mm fan. I have also added a speed controller to regulate the fan speed

Components Used:

1. 12V Fan
2. Speed Controller
3. DC Jack
4. Rocker Switch 15 x 10 mm
5. 5mm LED
6. Resistor - 580Ohm
7. 22 AWG Wires
8. Heatshrink Tube
9. Threaded Heat Insert
10. Activated Carbon Filter
11. Double-sided Tape
12. M3 x 12 Screws
13. M5 x 8 Screws
14. Rubber Feets

Tools Used:

1. Soldering Iron
2. 3D Printer
3. Wire Cutter
4. Wire Stripper
5. Hot Air Blower”
