It appears that Scientists have managed to adapt 3D metal printing to zero gravity, and have produced a small wrench.This is actually tougher than it sounds, since the powdered metals used can be explosive in the right (wrong?) proportions, and there is no gravity to hold them down.
This did not actually go into space, they produced the parts on a "vomit comet" flying a parabolic course.
Credit where credit is due, the pun comes from Arthur C. Clarke.
