Thank you for downloading PC Fan Desktop Air Purifier by Sheridan Lund inspired by Sarah Masih of Air Support Project.

Thank you for cleaning the AIR with me!

The way thingiverse describes the license is wrong, you are free to sell these if you want. No attribution needed, just clean the air please. CC0 is Public Domain, which essentially means it's manmade nature. Use it as you wish.

Purchasable as a kit from Sheridan Lund in the Mutual Aid DAO community Discord - https://discord.gg/N4gB328UK6

Nearly everything will be included in the MADAO purchase EXCEPT REFILLS(links here for refills):

3M p-100 Filters for 21USD in 2023 - https://www.amazon.com/3M-7093-P100-Particle-Filter/dp/B00EFC8BAU/

This may also work and would suffice for a whole year or two of operation(2091 is basic, 2097 has activated charcoal for odor filter) -- https://www.aliexpress.us/item/3256803967114429.html

If you are NOT purchasing with MADAO/USD you WILL NEED to purchase these as well; one of each and plug them together.
A PC fan, a power control module, a DC jack wire, and a USB 12v converter.
Then print the box, powerControl Housing, and 4 of the M5 screws in the folder. All other files are for development. Easy stuff
