Thanks for sharing this.
Do you have any thoughts on how this happened?
Me being 6'4" 220lbs, strong like bull and smart like tractor, was my first guess but upon inspection the plastic seems to be a two part pour that failed. In the pictures it looks like a partial pour, and the topped off, creating a weak spot. (I'm just reading that into the failed flow look of the center of the rod. Only a guess.)
