You might also need to trim the connector legs of the switch a bitinsert the 4/5mm steelball into the Runoutbody. place the switch with the hinged side of the lever towards the 1st layer.Fix the lever with 2 strands of filament through the awailable holes (heat up the ends with a solder iron to prevent it from falling out)solder the jst XH to C and NO (or NC) or just solder on wires directly.Close up the Body with the back piece and screw in a m3x10 screw. include the runoutsensor to your firmware and you are good to go.  [filament_switch_sensor runout_sensor] switch_pin: <PIN> pause_on_runout: true
