Simple Z-Axis Endstop holder V2 (OneUp/TwoUp)

This is a mild remake of Loclhst's excellent Z-Axis endstop.

I used an M3 16mm Bolt, and Nut

I had to modify it slightly, because although it worked for his OneUp perfectly, it didn't work well for my TwoUp. All I did was move the stuff around, and cut a nut holder. So honestly, all the credit goes to Loclhst.
