A really simple 3d printable soldering fume extractor that works suprisingly well.

It can be powered using a 3s lipo battery using a jst bettery connector. Or using a 5.5mm dc jack. You could also only install one of the options. There is also room for an on/off switch. The fan this is designed around is a 5010 fan. I used a 12 volt fan but that can of course be changed.

Hardware links (had all parts but found some that would work)(Switch and one of the power inputs can be skipped):

Can't find a link right now for the switch I used but still included the 19mm x12mm version

Also the .step file is available for any modifications you might want to do.

Happy printing!
