Fumes extractor with built-in power supply

For a very long time, I did not have a fumes extractor on my bench so while soldering I was often directly exposed to the fumes which are not good for my health. I wanted to build a fumes extractor that not only functions as it should but it also adds style and extra functionality to my bench so I integrated a breadboard power supply into it.

The base of the fumes extractor is made out of scrap piece of wood that I had in my basement and it houses the breadboard power supply as well as two pieces of iron that I've added for weight in order to be stable.

The 12cm fan is salvaged from a broken computer power supply and it is mounted on the wood base in such a way that it can swivel up and down to adjust the angle at which it gets sucks the air.

The output voltages from the breadboard power supply are brought to the front using some banana plugs that can then be used either with other banana plugs or with alligator clips. On the 4 connection points we have the input 12V from the mains adapter, the 5V, and 3.3V regulated outputs from the power supply and a common ground connection.

Out of everything, I'm really proud of how the wood base turned out as it looks amazing on my bench and I can say that this is one of my nicest pieces so far.
