Summary

A screw-on cap for a plastic gasoline container. Mouth is 1-11/16 inches in diameter. Threads are 4-TPI.

I made this using Tinkercad: https://www.tinkercad.com/things/2wsmz4URNnK

I printed this using PETG, but I think most commercial-grade caps are ABS. I'm not sure how different filaments hold up to gasoline.. I'm not a chemist. Use at your own risk.
