Make many copies of the same widget, select the most accurate one. Statistics work in your favor. There are microscopes that can resolve very small images, to help in selection. The microscopes are expensive, rent microscope time.

Maybe the techniques that stabilize microscope images, can be applied to 3D printer stability. The microscopes are not mass produced. Maybe 3D printing can reduce the cost of the microscopes. Contact Rich Didday rich@indecsystems.com . Tell him Dan sent you. He is very tolerant.
