Y-Clamp with stop
thingiverse
To activate the printer's y-stop, I used the clamp attaching the bed to the t-belt as a template. Modifying it, I created an arm that extends and hits the y-stop switch when the bed moves along the y-axis. This design is based on http://www.thingiverse.com/thing:30394. The part was printed with 2 loops and 30% infill; however, your results may vary.
