Simple Z axis adjustment helper - remixed

Original little extension saves me a lot of time and do not need a hex key to adjust. This remix puts the switch at the same z as the bed which is easier for me, maybe other people too. I use a straight edge from the bed to do the initial z adjustment. Note that the m nut is on the lower side like the original adjustment. Put the screw head on the bottom so most any knob can be used. The spring, washers and nut are from the original adjustment and a longer 35mm M3 screw. One more add on was a LED on the NO contact of the switch. On my machine the common is ground so the LED just goes from the middle contact through a resistor to V+. Z home turns the LED on.
