Z adjustable sainsmart endstop holder for Prusa i3

This holder is for a sainsmart mechanical endstop mounted on the Ø8 smooth rod.
I added two spacers between the endstop and its holder.
The screw holder is designed based on my machine but I think it will fit the most Prusa i3 printers.
You will need:
2x M3x12 screws and 2x M3 nuts for the endstop holder
1 M4x30 or longer screw, 1x M4 nut and a spring. Also wou will need two longer screws for the X stepper motor.
