Experimental cam generator for microswitches

This is a highly experimental cam generator for microswitches.
I generated a sample set for thhe westminster chime. The script is still very touchy and experimental. The cams do work, but they aren't the right size yet.
Maybe someone can use it for the base of a project, or even make a complete cam mechanism.
It seems the customizer can't handle some of the variables, so please open in openSCAD
