Take a look at the new version: https://www.thingiverse.com/thing:3322672

Bored of adjusting the bed everytime i change its thickness, I made my solution for z-axis endstop for my ANET A6.
Since the piece is very light, it is advisable to insert a spring between the screw and the fixed base, so as to crush the screw to the floor well.
