Prompt

Make a single solid consisting of a cube with a hemispherical dome fused onto its top face. Cube: 40mm × 40mm × 40mm, 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]). Dome: a hemisphere of radius 15mm sitting on top of the cube, centered on the Z axis. The flat (circular) face of the hemisphere is flush with the top face of the cube at z = 40, and the dome extends upward from there. The two parts are joined into a single solid (their shared circular interface is internal, not a face). Note: the kernel only has a full Sphere primitive — to get a hemisphere you must boolean a sphere with a half-space (e.g. intersect a sphere with a large cube positioned at z ≥ 40).
