This model is a remix from this one on thangs: https://thangs.com/designer/dbsorkin/3d-model/Creality%20K1%20carbon%20filter-893192

I printed it and was not satisfied with how poorly it mounted to the back of my K1C. It was loose and leaked air out of the sides.

I also found the instructions to be lacking.

I included the three magnet holders, but they are no longer necessary in my opinion - the new friction-fit is very sturdy. If you decide to use the magnets, you'll need 6 10x1 mm magnets

If you use the 3mf file, you will not need to make any specific infill tweaks for the grilles to print correctly. In the original post, the creator states that zero top and bottom layers of the grilles. I added some modifiers to leave the corners solid, which will save you some effort.

The bottom grille is optional. I opted not to use it for better airflow. I placed activated charcoal (to reduce VOCs) in the top section, so the top/middle grilles keep the charcoal contained, and the lower section is just a duct. The top grille is superglued in place, the middle grille is held in place when the top and bottom parts are screwed together.

You will need:

- super glue to mount the upper grille to the upper body and lower grille to the lower body

- 4x M3x8 screws with coarse thread

- PETG
