Air Purifier v2

The top needs work. The current design is too delicate. I will have a ‘set-on’ top that will be much better and without those pesky pegs that break. Less material also, I plan to make it pretty thin.

I always prefer using Polymaker filaments. They print very well even when not perfectly dry. Very forgiving filament. Below are some affiliate links to my favorites on Amazon:

Polymaker PETG Black https://amzn.to/3N6CKSk

Polymaker PLA PRO https://amzn.to/3NfYmeU

This Polymaker dry box is awesome. By far the best box out there. Doubles as storage and comes with a great feed tube to use as a holder for printing. Check it out https://amzn.to/3YvOtfB

These use generic filters from amazon: https://amzn.to/3NaVhwG

The design was CFD flow tested using this fan: https://amzn.to/49oAdKz

Gen 2 Fan (not tested, double check dimensions work the same as above) https://amzn.to/3LAAeDg

You can print as many inner tubes (filter element supports) as you like, they are stack-able. 1,2,3, etc… filters is possible. 

Works rather well with the iPPC3000 Noctua fans (need the head pressure and CFM flow of these industrial fans).

The top cover sits on the fan with four small alignment pegs. they are very delicate. Printing in 3 or 4 perimeters should make them solid. 

Print the top nut with the square side down, for thread quality. Print the Grid Lid top side down, no supports required for the angled fins. Other parts right-side up.
