Description
A simple and small adapter to fit a 140mm fan onto a xiaomi air purifier filter.
It's about 170x170x13mm, so it should fit on most printers - mine is 200x200 so all the more popular filter adapters didn't fit.
Print it flat, infill doesn't matter.
You might need to get some electrical tape and tape the ring to make it push fit. I had to do at least three layers of tape to make it perfect.
I used Arctic P14 Pro fan with a USB-C PD trigger board. This fan is more than enough to draw air through the filter (can be seen on the second picture).
