I’m trying to 3D print Sunshades for my scopes. I have a few people wanting me to make them some also. So I’m thinking if I can find some way to get accurate threads for basically any scope, it’ll be a little side money help for me.

Does anyone know how to accurately measure, or where (maybe a reference chart) I can find specific thread sizes and counts of basically any thread size? I have read a little, and if I understand it correctly, I can use my mic and measure the highest points of threads for the size, but I’m stuck on the pitch/count on such fine threads. However, that doesn’t help me, because if I’m needing to cut outside threads, I need the size of the inside threads.

Any suggestions?
