Prompt
Make a single solid consisting of two cylinders fused together. Big cylinder: outside diameter 50mm, axis along Z, base on the XY plane (z = 0 to z = 40), centered on the Z axis. Small cylinder: outside diameter 10mm, axis along Z, base on the XY plane (z = 0 to z = 40), positioned so that its outer surface is externally tangent to the big cylinder's outer surface on the +X side. The two cylinders share exactly one tangent line (no overlap, no gap). Output a single solid (the union of the two cylinders).
