Water-Based Air Purifier

thingiverse

This all started with a challenge from a friend to bring my ideas to life. I took up the gauntlet. The idea came from living abroad, where people would hang their laundry outside and rain would wash away pollutants. Why couldn't we do something similar without getting dirty? Every single part (except for one) can be printed using a 15x15x15 cm printer. There are three versions in these pictures: Version #1 - The Concept: By designing the fan blade skeleton with diagonal bars, I could print it cheaply. I sewed water-wicking fabric over the blades so they'd stretch easily and used a 3D pen to assemble them. Version #2 - The Build: To make assembly easier, I added tabs and holes for screws and bolts. A heat gun helps seal joints, or you can use flexible filament to create a gasket. Version #3 - The Mobility: Both versions broke when dropped, so I redesigned the blades to be thicker and streamlined the attachment system. I also added a finger guard with space for a logo and made a base that fits on a flat bottom or has rails for an array setup. The files are for version #3. The bearing holder is separate, allowing you to customize it to fit your chosen bearing style. Bonus notes: * There's a dimple at the top of the driver where you can drill a small hole for motor attachment. When adding the bearing holder and bearing, there'll be enough room for a tube - this is the water inlet. If you use a large enough bearing, you can add strength by using a metal straw or car brake hose as your attachment. * I designed it with customization in mind, but didn't get into any Arduino projects. I'd love to see what the community comes up with! * By using PLA, I reduced costs and made it recyclable. It's exciting to think about cities transforming through local people solving issues in an environmentally friendly way. Imagine if cities subsidized local innovation!
