Filtered Exhaust Fan Bracket
thingiverse
This is a bracket and enclosure to pair a standard PC case fan with a charcoal filter to create a basic fume extractor for use in soldering, but it should be useful for 3d printing or any other fume-producing operation. I used [these filters sourced from Adafruit](https://www.adafruit.com/product/3836). The compiled STLs are made for a 92mm case fan (just what i had lying around) but the provided OpenSCAD code is fully parametric; just change the `fan_size` and `hole_spacing` variables to match your fan. There is a tab on one side to aid in mounting. the hooks to hold it closed are intentionally designed to be a fairly tight fit; you may need to adjust them depending on your printer's dimensional accuracy.
