      A micro injection molding tolerance stack explains why individually acceptable features can still produce a loose, tight, misaligned, or nonfunctional assembly. At small scale, datum construction, cavity variation, directional shrinkage, insert position, measurement uncertainty, and mating-part error can consume clearance quickly. The practical solution is to build the stack around the function, separate sources of variation, and verify the model with assembled evidence. Tightening every drawing dimension usually increases inspection and tooling burden without guaranteeing fit.
