The Lotus Evora start button has a white light in it that really wipes out your night vision. On the bridge of a ship, there are no white lights at all, as sailors know how valuable night vision is. So, I drew up and printed this cover, which I glued to the start button with some contact cement. No more problem with that one. There are several other white lights, but this one was the worst, so "it's fixed."

I printed it in ABS. I tried nylon, but didn't like the look. Two versions are here, one with raised and one with sunken letters. Source code included.
