Lawnmower Gas Cap

I lost the gas cap on my lawnmower. A LLM designed a replacement cap I can print. It is designed to fit onto a gas tank nozzle with exterior threads and the following dimensions.
- inner diameter (smooth): 1-5/16 inches
- major outer diameter (total, from outside of threads): 1-5/8 inches
- minor outer diameter (from inside of threads): 1-3/8 inches
- length: 5/8 inches
- thread density: 7 threads/inch
