This project is comprised of three primary components: a 3D-printed housing, a fan, and an activated carbon filter. Links to everything you'll need is in the parts list above.

Choosing a fan

You have two options for your 80mm fan -- you can either solder your own fan circuit and add your own switch, or use one that's plug-and-play.

To save time, I'm using a 5V fan with a switch and wire built in. You can probably save a few bucks by soldering your own fan circuit, but the one I'm using is quite powerful and is only about $11. The downside is this fan has a lower CFM, meaning you'll need to keep it closer to what you're soldering.

If you prefer a higher CFM fan, you can find one on Amazon, though you may need to bump up to a 12V fan to get a really high CFM.

If you'd like to solder your own fan circuit instead of using a USB fan, see the instructions on Instructables.
