This is my build of the "Solder Fume Extractor, with Custom Filter for Activated Charcoal" by JustJirHere that he published on Thingiverse. It has been redesigned to replace the 80mm fan with a 120mm fan. Also I have added a DC power jack so the fan can be powered from a standard 12V power brick.
3D printing
Most of the build time is in the 3D printing of the parts. They are as follows:
"Filter Fan Holder 120mm - Top.stl" - 0.2mm layer height, no supports
"Filter Fan Holder 120mm - Lid.stl" - 0.2mm layer height, no supports
"Filter Fan Holder 120mm - Base.stl" - 0.2mm layer height, no supports
"Filter Fan Holder 120mm - Case.stl" - 0.2mm layer height with supports (preferable tree supports if your slicer supports…

Assembly
Firstly you need to ensure that the fan is facing the correct way. It needs to blow air out the back. This means the fan label needs to be facing the rear of the case.
Next you need to cut the fan wires to around 6cm. Wire the fan to the DC power connector ensuring the red wire goes to the 12V pin and the black wire goes to the GND pin. If you fan has 3 or 4 wires, leave the others unconnected.
Wire the fan to the DC power connector
Test the fan by plugging in a 12V supply. Slide the fan into the case ensuring that the power socket is in the corner that has the mount for it. Also ensure the label on the fan is facing the back (The back-side has the 4 mounting holes for the fan).
When the fan is about half way in, push the DC socket into the hole provided. It is a tight fit but should go in without too much force. Once in place add two 6mm M2 screws to hold it in place.
The DC power socket is pushed in so it is flush with the outside of the case
Align the fan with its mount holes and place the fan grill on the outside of the case. Screw in the fan using four fan screws.
Cut the Activated Carbon Foam to fit the foam holder. Close up the holder and slide the holder into the case.

Now you can apply power and ensure your Solder Fume Extractor works as advertised. Once you are happy with its operation, super glue on the top cover to cover the fan.

Conclusion
A simple but useful build that will eliminate those dangerous fumes when soldering your future projects. Thanks JustJirHere for the design and inspiration.
