Pretty good Solarpunk prompt with some medium-hard sci-fi thrown in.

Im talking precision of things like the screws in the hvac system. Manufacturing relies on other manufacturing that relies in the first manufacturing type of thing. So like how good a clean room can we cobble together to make how decent a cpu today. I certainly know the clean rooms of the past allowed in much to high a size particle to be used with our latest chips today.

Oh, then we just use 1000:1 reduction techniques that are over 200 years old. We would only need a single long screw to bootstrap modern manufacturing without any other machine tools.

All the details required to get to 0.1mm precision can be found in this book series
