That's seems to be the case most 3d printed contraptions. Extrude a framework, and the populate it with a bunch of traditionally manufactured parts, but then call it a revolution.
It's a disappointing pattern, but somewhat understandable given the state of the technology.
Came here to write this as well. I mean, I was hoping this wasn't one of those cases, because then it would be a true revolution. But alas, it's another "print a different frame for the professionally manufactured thing".
