The fumes produced by soldering iron and soldering wire (specially the leaded wires) are not good for you health. A good fume extractor, at least here in Brazil, can be expensive. So, I decided to make my own.

• The printed objects from this project
• An 8cm x 8cm computer cooler fan
• Female panel mount DC power jack
• Male DC power jack
• 12V DC power supply (see the power consumption of the fan to define its characteristics)
• DC power switch
• Green/yellow cleaning sponge (to get the "filter" from)
• Zipties (I needed 2)

1) Make 2 holes on the box of the bottom part: one for the female power jack, other for the switch
2) Put the cooler on the bottom part
3) Put the top part over the cooler
4) Tie the top and bottom using some zipties
5) Solder the wires on the female power jack / switch
6) Solder the Male power jack on the power supply 12V wires
7) Install the switch and the female power

Optionally
1) Put the boxbottom part

There is a model for a Gopro mount, to be glued to the bottom of the bottom part, but I just made it because I have lots of gopro suff.

The openscad file to this part needs a library, available on this project: http://www.thingiverse.com/thing:62800

Download the file "gopro_mounts_mooncactus.scad" and put it in the OpenSCAD library folder
