Hi guys.
Since mother Google didnt help me at all, Im posting my question here.
Im trying to find dimensions for pins that comes on the back side of badges but couldnt find any photos on the internet.
I need to know the distance between centres, their diameter and height.
If someone could post them here (in best case with some photos of mesaruments) you would save my day.
I need them for a 3D printing project.

P.S. is the 82 and 74mm badges for all models or there are some other options that I should know of?
