This is a protection/ grill for the 60mm back fan in the Creality K1C to protect it from flying or loose parts. I supposed Creality K1 also has one at the back.
There was once that my print did not adhere to the textured PEI plate (Creality Plate B) and flew off mid print. “Grr” followed by a “tud” was heard as the 2mm PETG rod hit the back fan.
I was glad that no real damage is done. Didn't find a easy-to-install back fan protection and decided to create one myself.
This installs over the skimpy metal fan grill (that came with the Creality K1C). You can choose to install the in any orientation to have the 45 degrees opening facing downwards or towards the sides.
How I printed it
