Making the assumption that there will have some amount of weight on it, I've made a very short version of salzig's LACK table stacker model, thickened the walls a bit, resized the leg "receiver" hole a bit and beveled the edge to account for elephant's foot, filleted many of the sharp corners, and added a "base" so that the receiver forms a cup, to keep it from sliding up on the leg.
Works great.
