My old boss used to say a good design needs a six inch gap for a hand holding a wrench. Your electrician story is exactly why, lily_young59. We spend so much time making the 3D model look perfect that we forget about real arms and tools. I keep a picture of a guy trying to fit into a service space taped to my monitor now. It's the best reminder that someone has to actually build and fix the stuff we draw.

My uncle had a whole set of those emerald green Victorian encyclopedias. I bought a box of nitrile gloves from the hardware store and a pack of zip-lock bags. I wiped each cover down with a dry microfiber cloth while wearing the gloves, then sealed them individually. They're fine on the shelf now, just don't touch them.

My old truck seat taught me the same thing about posture.

My old shop in Toledo had the same "close enough" attitude until we started on a batch of custom headers. The cheap test strips we used were always giving different shades of green. Switched to a refractometer and had to learn that the blue line is the one you actually read, not the shadow.

Felt that crunch in my soul.
