I like it, but one thing stood out to me. Sharp corners in the path of a non-moulded seal can cause leakage and premature failure. I recommend that each of the four walls not terminate in a sharp corner with the round, but a small radius. Then the seal could make more gentle bends in front of the holes, instead of wrapping around them, taking an octagonal path around the part. Also, those deep corners are not readily CNC machinable, if you ever wanted to go that route.
