3d Printer End Stop Made from Scratch

I needed end stops for my printer and, since it's always more fun to make than to buy, this Thing is what I came up with.

I wanted a single design flexible enough that I can use for all six end stops, and I wanted it to be somewhat adjustable in both the mount and the trigger point. The STL files here make three different parts: the end stop itself and two mounts, one designed for horizontal and one for vertical use. A single openSCAD source file codes all three - there are selector variables
