Z-Stop for Z-Morph Personal Fabricator

The stop for the Z limit switch broke on our Personal Fabricator the other day. We set out to improve on the design. For one thing, you have to remove the entire rod it mounts on to slide it off. The other thing is that it is really hard to make fine adjustments to home the Z axis. So we made a cavity for an M6 nut through which an M6 bolt threads into to make fine adjustments to the Z stop.
