Distance from turning mirror to detector plane

We took advantage of having the flip mirror side-wall exposed today and measured the distance from the center of the turning mirror to detector plane.

Using calipers, the center of the turning mirror to the outer edge of the O-box wall is 3.24"~ 82mm

The detector plane is 10.9 mm from the outer edge of the O-box wall.
This value was obtained using the SolidWorks drawing of the D-box, and adjusting/assuming the following values:
        1) The G-10 standoffs are 4.445mm in the drawing, but for CD013 are actually 3.82mm.
        2) Assumed that the detector plane is 6.35mm behind the front cover of the detector socket.

Our calculation puts the detector plane 10.9 mm away from the outer edge of the O-box wall or
93 mm (3.66") from the center of the turning mirror (for CD013).
