May 2024 - v3 top is coming soon. 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.
These use generic filters from amazon:
Fan:
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.
