12V Fume extractor composed of a recycled CPU fan, two 9V batteries with a 12V regulator, a switch, and a 3D printed case. The model contains a spreadsheet where you can resize the box to fit your own fan. The model was made with the in-development version of FreeCAD, so it is finnicky and sometimes doesn't quite work as expected.

 

The extractor can pull fumes from over 8in away from it's face. It is to be used in conjunction with any carbon filter you can find. Amazon sells rolls of carbon filters that you can cut to size for about 15c a piece.
