Prompt

Make a single solid that is the union of two cylinders intersecting at right angles. Vertical cylinder: outside diameter 20mm, length 40mm, axis along Z, base on the XY plane (z = 0 to z = 40), centered on the Z axis. Horizontal cylinder: outside diameter 20mm, length 40mm, axis along the X axis, centered at (0, 0, 20) (so it passes through the middle of the vertical cylinder). The two cylinders are merged into one solid (their intersection region counts only once).
