It was a lovely intersection of difficult materials (400-series stainless), precision (there are several bad things that happen if things inside the housing get hit with an endmill), and difficult requirements ("no" chips can be left in the housing, the housing cannot be opened, the housing cannot be flushed with water).
I was happy as a clam. Very satisfying work.
