This is a side BTT Eddy mount for the Creality K1/Max. It takes the position of the lidar mount. I use the existing toolhead cover screw, and two other smaller self threading screws to hold the mount in place (These 2 screws are existing parts from my K1 - didn't need to purchase any other building materials). The BTT Eddy comes with M3 screws you can use to screw the it onto the mount.
To try out BTT Eddy on a stock K1, you can use the Guppy K1 Klipper Mod. Full guide on how setup the BTT Eddy on a stock K1 can be found here https://ballaswag.github.io/blog/creality-k1-btt-eddy-guide/
