Diameter of Stand on Indoor Camera 2nd Generation

I'm trying to 3D print a holder for my parent's Ring camera and I can't seem to find the diameter of just the base stand that comes with the camera.  All of the dimensions listed on the website include the security cover which would be wider than the base.  Can someone give me the dimensions of just the base of the camera?  FYI - They are elderly and it would be tough for them to give me an accurate measurement and they don't live nearby so I can't measure it myself.  Thanks in advance!
