This is a support for ventilation and filtration the air in the area where you are soldering so that you won't inhale the dangerous fumes generated by the process of soldering eletronic components.
Video of the ventilator working:
The parts you will need:
4 x Ventilators (40mm x 40mm x 10mm);
Cable (I used 22AWG, but you can use others like 24AWG);
Switch button with 2 connector (30mm x 10mm);
Connector for 5V charger;
Carbon activated filter (130mm x 130mmx 11mm);
M4 x 50mm screw;
Both base and frame were printed without supports. All the channels alow to pass the wires, it may be a bit tricky to pass the ventilators wires inside the frame, but with a bit of perseverance they pass and stay hidden for a cleaner look.
Post your prints in the comment section! ;)
This is a side cut to be able to see where the wires pass in the base part. In the front there is the cut for the switch, towards the back there is the hole to pass the 5v power and ground wires coming from the charger wich connects to the switch
This is a top cut to be able to see where the ventilators wires pass inside the frame
