This is a mod for the KOTTO fume extractor.
Required parts:
KOTTO Fume extractor
120mm X 120mm X 38mm, DC fan. I used the SUNON MEC0381V1-000U-A99, which is a high speed 12VDC affordable fan (6.70 CHF or ~7EUR on conrad.ch)
USB-C Trigger board (a.k.a. USB-C decoy), I used https://de.aliexpress.com/item/1005008233128518.html
2 zipties
Print with no supports. I used 0.2mm layer height, 40% infill and 4 perimeters, but anything should work. Slide the existing hardware into the circular openings and use zipties to attach the USB-C trigger board.
Replacing the stock (mains power) fan with a lower voltage DC fan should be safer, but electricity is still dangerous. You do so at your own risk.
