I had issues with the switch bracket for the K1 Max as follows.
Bracket was slightly too low and the print head point kept ramming the bracket before making contact with the switch.
Print head kept hitting the bracket on Mesh.
Bracket was easy to move after installed.
Changes I made
Increased height by 2mm
Added tab to mounting point for a more snug and secure fit into the stepper bracket notch.
Moved switch pcb mounting holes, the board no longer extends past the bracket and moves the pcb slightly forward to allow the bracket to recess more..
Slid mount back 3mm to prevent print head hitting from hitting bracket on mesh.
Added cutout for more distance from belt and pulleys.
Changed hole depth to accomodate M3X8 screw.
Added thin layer of material to screw hole. This layer is easy to punch through and prevents material sag.

It seems it's not public. Tinkercad says the object is missing. I'd also suggest putting it on Printables as a remix of mine, so others can see it.
Nice!
