Day 6: Cupcake CNC Optoendstop Trigger for X Minimum (Q42450)

I'm trying to upload a Thing-a-day this February. makerblock.com/2011/02/makerblock-thing-a-day/ I've put the opto-endstops back into my Cupcake! I had taken the endstops out because they weren't necessary for normal safe operation and tended to get a little cumbersome. However, in the hopes of creating some auto-homing GCode, I've re-installed them. At best I had a very jury rigged endstop trigger. This is intended as a workable fixture.
