Piper1 endstop switch mounts, customizable

I didn't like the idea of optical endstops. I mounted regular, mechanical switch endstops. I had two types: smaller (black and white), M2 screws, separated by 6.5mm, and larger (green), M2.5 screws, separated by 9.5mm. I used smaller one for X axis and larger for Y and Z axes. However, with the OpenSCAD source this can be changed.

Mount the X endstop on the left Z-roller bracket, near the X motor, facing the X carriage. Mount the Y and Z endstops on pipes: Y behind one of the rollers so the roller can trigger the endstop, Z under one of the Z-rollers, facing the bed.
