USB Extractor fan

thingiverse

I needed an Extractor Fan to vent out Resin fumes while printing in my study. I then remembered that I have an USB desk fan that we weren't using and thought that I could print an attachment for that to extract the fumes as it was surprisingly strong. But then it hit me... I could just design an extractor fan body, and strip the parts from the desk fan! And that's exactly what I did. I ended up using a very old phone charger that I found in my box of wires, which was rated similarly to USB and a spare rocker switch. But you could technically edit the f3d and reuse the USB cable and switch that is already on the fan and not waste parts. (I am saving those for future projects)
