Broken Leg Clip

I tested one of the partially completed leg clips where I'd run out of filament. As expected, it broke at the narrow back end, which is generally the weakest point with the most leverage on it, but I had to get it pretty wide to make it break. I was not able to break the two remaining curves by hand at all. Again, I'll beef up the slot a bit to ensure it holds, since I also plan to increase the capture force on the clip even further.
