Prompt

Make a stepped-bore ring as a single solid. The outer body is a cylinder of diameter 80mm and height 50mm, base on the XY plane (z = 0 to z = 50), centered on the Z axis. From the bottom face, subtract a coaxial blind bore of diameter 30mm that extends 25mm deep (z = 0 to z = 25). From the top face, subtract a coaxial blind bore of diameter 50mm that extends 25mm deep (z = 25 to z = 50). The two bores meet exactly at z = 25, forming a stepped interior: a narrow (30mm) chamber below and a wide (50mm) chamber above, connected at the mid-plane. The outer wall is 25mm thick at the bottom half and 15mm thick at the top half. Output a single solid.
