Donw, I know, but it is a weak qualifier, sure by part count the thing is 50% reproducible, but my proportion almost none is e.g. the metal bars. Its kind of like saying that your desktop printer can reproduce itself by printing layers of paper that can be cut and glued together. I bet someone could do something, but it is unlikely.
By proportion, you're 0% reproducible; you consist entirely of atoms that must be sourced from the environment.
The relevant thing is the availability of the needed parts from the environment and the amount of human effort needed to carry out the replication. At this point the needed parts are widely available and cheap in the US, but sometimes hard to find in other places, but it doesn't look like that's the real problem. And the time to assemble the new machine once you have the parts isn't a big problem. The current problem, as far as I can tell from reading the blogs, is that the machine isn't yet reliable enough to reproduce itself in a lights-off fashion. You have to keep fixing it.
