Grey is the quiet colour on the functional shelf, and the one engineers tend to standardise on. It shows geometry clearly under workshop lighting, which makes it useful for checking a design before committing to a batch, and it hides layer lines better than a bright shade. Parts printed in grey PETG blend in when fitted to existing machinery instead of announcing that they were made downstairs. The material handles repeated assembly and disassembly without the edges crumbling, so test fixtures stay usable across several revisions rather than being reprinted each time.
