Prompt

Start with a 40mm cube, centered in X and Y with the bottom face on the XY plane (so it spans x in [-20, 20], y in [-20, 20], z in [0, 40]). Cut a rectangular pocket into the top face: remove material in x in [-10, 10], y in [-10, 10], z in [30, 40]. The pocket is open at the top, closed on the four sides and the bottom (10mm of cube remains underneath the pocket). Output a single solid.
