quest 2 controller dimentions

I'm trying to create a project and haven't been able to find any help on the intricate dimensions of the quest 2 controllers by this I'm talking about the exact diameter of the top and bottom of the ring and the angle between the top and bottom of the ring as well as all other dimensions but mainly the prior mentioned. The closed I've gotten to anything was a 3d model of the quest controller which I haven't been able to transfer into my CAD software so I haven't been able to get dimensions off of there. If there really is no help then would I just need to use a pair of digital callipers and combination square and gather the measurements my self?
