ok, my caliper is on (inches)…
2.5 on the dot for height, 5.73 width, 1.7 depth. On the bottom is a pill shaped plate that is a tad bit thicker than 1/8 inch; .153". This plate does not extrude pass the main body of the casing.
If you want any more messages, just ask. (soon rather than later because once we mount these things, it may be a little bit of a problem getting the measurements.
