Created a Bender inspired soldering fume extractor. Uses a rocker switch, 12v power supply, 70mm fan and carbon filter. Be sure to get a high volume fan vs a quiet fan. My first attempt using a quiet fan it just didn't move enough air volume.

There are 2mm holes to use 16-20mm long screws. Screws are on the bottom to hold the teeth. 2 on the side, near the bottom to hold the base. 2 on the visor to attach to the head. Remaining parts should be downloaded from original diagram, which has a nice graphic of how things are put together. https://www.thingiverse.com/thing:4384974

I printed with tree supports for most of it just to keep the bridging to a minimum, but YMMV.
