A design to make the z-axis limit switch of the Anet A6 adjustable. I made this to accomodate a glass plate for my heated bed.

The slider is mounted with an M4 bolt, a nut is fixed in the back of the z-axis cap.
Beware that you keep the cable of the limit switch free of the moving parts! The cable of the original limit switch is long enough to move it to this position, so no soldering required.

You may need to file away some material on the slider / cap to make it all fit. Also the mounting holes of the limit switch are too small. I used a 1,5mm drill to make the screws fit.

Happy printing!
