My only concern is that pipe c is shown as having two different shapes: straight and slightly curved.
Based on the fact that the design requires that a and b be different, there would undoubtedly be the same situation for the four slightly curved c pipes. That is, there would need to be two “c2” pipes and two “c3” pipes in the set rather than just four more of the same c pipe.
That makes me think the diagram at the bottom was made before a decision to cut costs and/or simplify. Four regular c pipes will undoubtedly be cheaper and logistically simpler to manage for both shipping and user construction than having those two extra pipe types.
It was, of course, relabelled to match the supplied parts, but the hints of the original design still remain.
Makes sense to me.
