This are 2 mounting points for a 30x15mm cablechain for the Z-axis of the Anycubic Chiron.
The upper mount goes over the stepper motor of the X-axis and uses the same screw points like it. You will need some longer M3 screws for screwing it on. The lower mount goes on the frame profile and will be screwed on with 4 M4 screws and t-nuts.
