The RepRap project sorta hit some of your points. It was more about establishing and spreading 3D printers. Evangelizing them. One printer would print all the plastic parts for to make another 3d printer. This could then be given away or sold. Things like screws, rods, motors, and controllers were “vitamins” that need to be added to make the printer. Obviously people were doing the assembly not the printers. They also violated your rule #5 because they could do tasks besides replicating.
My second printer was a Prusa MK3S+. It’s heritage came out of RepRap and a lot of its parts were 3d printed.
