This is my most complex design so far, but it's still fairly simple in the great scheme of things. The faceplate mounting measurements are from the official data-sheet:
The main shell is basically an extruded projection of the angled faceplate. The mounting tabs are all just rectangles with cylinders removed.
If folks are interested (let me know in the comments), I may be able to put together a parametric version for different mounting heights / case depths.
