Do you have access to a precision measurement tool like a caliper?
if you can leasure the thread outer diameter (called major diameter) and the distance between the 4 peak of the thread you might be able to confirm which one it is.
I no longer have a oops ASA so cant check for you

Palmers has stuff like this https://palmerspursuit.com/products/...-female-asa-to and I assume from the names on them that an asa is .825” @14 tpi but, there are still other critical dimensions like the distance between the o-rings and such but I suppose if you measure enough you can get all that info
Edit: I misunderstood, I thought you wanted ASA thread size specifically, you need the knob's thread. You can always just take the part into home depot they usually have a little display with a built in threadguage. I wouldn't be surprised if it was normal ASA threads on the knob too.Last edited by Euphie; 07-22-2021, 10:07 AM.

Oops asa threading
I have trouble gripping/turning the knob on my Oops asa and want to 3d print a new one. I have had no luck finding any online, but I know I can model one.
My problem is I don't have access to any kind of thread gauges at home. Does anyone know the thread for the asa knob?
