Elastic Shoelace Pull

I use elastic shoelaces to workaround tying shoelaces. The elastic shoelaces last a long time, but the end cord pull (especially the hinged clasp type) is easy to misplace or damage, so I've designed one that is easy to print. This should work for many standard elastic shoelaces at its default size, but should be easy to scale up or down if needed. I print it using PLA with about 50% infill to give it strength and heft. Print it with the small end down, and use an outside brim, if needed.
