Y-Axis Stop Upgrade for Prusa i3 3D Printer

The new part triggering the microswitch. Success!
Since day one of using Crystal Palace, my Reprapguru Prusa i3 V2 clone, I've been planning to fix the poor design of the y-axis stop switch. The Reprapguru design is annoying but marginally usable with careful adjustment and frequent human intervention, but after making a small bumper part on the 3D printer and screwing it to the bearing housing (all of forty minutes of effort) the problem is solved and I don't have to worry about it anymore. Not bad for a full year of irritation and procrastination!
