This is a replacement for the 12032 side fan exhaust on the K1/K1 Max. I've added some tabs on top of this model to make it compatible with U design's lightbar fan Mod. https://www.printables.com/model/668103-side-fan-led-mount-for-creality-k1

I wouldn't recommend using it for the left side fan (assuming you have one) if you have a creality camera installed because the lights would shine right at the camera.

It should stay on a bit better than the stock tabs as well since they're a bit more pronounced. It is a bit harder to get on and off though.
