Microswitch Models

Parametric OpenScad Models for 3 sizes of microswitches.

Variable $EC holds the extrusion correction.  This value will expand the model and shrink the holes by $EC.
This allows the model to be subtracted from the an volume to produce a snug fit into that volume

Variable Holes=true generates two 2d circles where the holes are placed ($EC still applies) and can be used
to generate holes in a positive volume for mountng.
