Chevy Headlight Adjusting Nut

thingiverse

Here's my rendition of the headlight adjustment nut for most GM trucks in the 1980s, as well as some of the 70s and 90s. It is greatly reinforced compared to the cheap flimsy replacements available today, and if printed from a flexible and heat-resistant material should last for years. I used ABS, but PETG or Nylon would probably also work just as well or even better.
