To build it with that accuracy would be physically impossible. Guess he forgot about thermal expansion and contraction. Guess he forgot about the weather...
Nah, not impossible people build stellarator type Fusion reactors with large freeform metal parts in that tolerance region that are exposed to liquid helium.
Does not change the fact that all materials expand when temperature rises and contract when temperature cools. Plus different materials have different temperature expansion coefficients.
Most. Water, for example, takes up more volume in spaces when frozen
True, water is weird like that.
