You'd be surprised! I was a custom microscope parts maker during my time in academia, mostly one offs but a couple fun things that we shared with our collaborators. Surely not at your level of precision, but I did my tour of duty in academia for ~10y, and was none the richer for it. I can only imagine the toys you have, We had a great machinist who was an ex-tool and die guy in our department, was a dream to work with. This work was my first love, but the American student debt system caught up with me. So it goes.
