Summary

A printable air filter based on widely available known brands. The pieces only fit the IKEA filter atm, but the pieces should be pretty easily adjustable for any filter size.

This is v1 and is very much a beta. Doesn't look the best, the clips on the corners are flaky. But it does work just fine. I even cut the wire hole with a knife, because i was just so done with this project at that point :D because this works just fine v2 will probably never come. moving on to an air humidifier next.

Printing

I tried my best to keep the count of different pieces low. Right now here's what you need to print for a full set:

• 5 vent pieces
• 5 block pieces
• 4 corners
• 12 clips
• 8 corner clips (PETG)

Everything is printed without supports, but check the orientation.
Everything is printed in PLA, except for the corner clips. PETG is the way to go here for some needed flexibility. But I never tried the final version in PLA, might just work actually.

Putting it together

It should all be very apparent. The best suction should be with 3 vents on the top and 2 at the side-bottom. Clips hold it together. Corners use "corner clips" to keep the build snug. And vents screw on with the screws that the fans come with.

Summary

This was a fun project, but honestly woodworking this makes way more sense. I just didn't have a workshop handy. But now that the pieces are designed i wouldn't mind printing the parts again. Much cheaper and more effective than the IKEA own machines.
