I'll do you one better and model one up in the next couple days if you like. Surprisingly, the chamfer isn't at 45 degrees, it's steeper. The lens is 11.35mm x 11.25mm at the base, 10.3mm x 10.5mm at the top (or very close to it, difficult to measure with a caliper), and 1.5mm high. The box itself is 12.6mm x 12.4mm, 11mm high.
