3D Chameleon switch mount for Bambu P1P

The original switch bracket hits a rib on the back of the machine, and makes the switch deflect upwards. It was causing inconsistent triggering of the switch. I add a recess on the back of the bracket, so it would mount flat on the back of the machine. 

I only have the P1P, but presumably this wouldn't be needed on the X1, or a P1P that has side panels, as the rib would probably be covered.
