Solder fumes extractor using a 45mm fan

Soldering fumes are, at least, uncomfortable. More if you have to solder some huge PCBs during hours. In those situations I use to put a computer fan in my workbench to blow them off. The problem: a 10mm width fan is not quite stable, so I decided to make a quick openScad script to give it a nice base.
