Hollow cylindrical cap with 8mm base wall A · A5 · a5-hollow-cap-01

Expected

Prompt

Make a hollow cylindrical cap (like a cup or thimble) as a single solid. The outer body is a cylinder of diameter 60mm and height 50mm, base on the XY plane (z = 0 to z = 50), centered on the Z axis. The inside of the cap is hollow: subtract a coaxial inner cylinder of diameter 50mm and height 42mm that opens from the top (z = 8 to z = 50), leaving a solid base wall 8mm thick at the bottom (z = 0 to z = 8) and a cylindrical wall 5mm thick all around. The top is open. Output a single solid.
