You'd be surprised where 3d printing has gone in the last few years. Maybe it's not to the point that your clock project would be feasible today, but well tuned homebrew 3d printers already surpass the accuracy and resolution of many commercial printers. Check this out as an example. The technology is improving and becoming more accessible. If you told someone looking at the first Altair that one day they'd use a similar machine to share intimate details of their lives with strangers on the other side of the planet they probably wouldn't have believed you, but here we are.
