Grandkids loved dalgibbard's remix, but would break the legs after some overly active play. I tried to beef up the design a bit where it was breaking at the interface between the legs and the body. I think I can still add back the arch, but this worked pretty good, and seems to be compatible with the original remix so I'm publishing as-is for now. I haven't tried the multi-piece original design so I can't comment on compatibility. Software failing me on one leg's corner radii. Will fix sometime. Print with the track face down, use supports, and I used 15% infill. Credit to dalgibbard for the remix I used to start this remix.
