The brush holder is designed for Ender 3 series not S1 and for the silicone brush from Bambulab A1 mini. It is used to be gentle on the brass nozzle.
There are two choices right side or left . I recommend printing 3 washers under the other bed screws which I have also included in the 3mf.
The gcode for cleaning the nozzle you have to make yourself as everyone tightens the bed bolts differently therefore the brush will be at different heights. I recommend to home all axes, drive to the bracket in manual mode and carefully. write down the necessary coordinates of all axes and create a macro for the Klipper accordingly or enter it in the start gcode in the slicer at the marlin to clean the nozzle.
