Henlor's run out sensor for the Creality K1/K1C/K1M required a 1x M2 x 8mm self tapping screw which I didn't want to bother finding locally so I designed this block in Blender to insert to prevent the switch from moving around doing the job of the screw.

Use this on your printer at your own risk, it may trigger false run out if not the right thickness

Scale it on the Z axis so that it sits flush with the body, it may take a few prints to get it dialed in just right but thankfully they print fast.

I printed it at .28, 6 walls 4 top 4 bottom with 20% 3d honeycomb infill
