The prompt
"Create a 3D parametric mechanical part to act as an alignment guide for watch hand installation on a Seiko VK63 movement. The model must be a hollow cylinder with a total outer diameter of 34.0mm and a total height of 12.0mm. The bottom opening must have an exact inner diameter of 29.1mm extending upward by 8.0mm to securely friction-fit over the 29.0mm casing diameter of a VK63 chronograph movement. At the 8.0mm height mark, create an internal shoulder/shelf that transitions into a narrow upper guide hole with an internal diameter of 4.5mm. The top surface of the cylinder must feature a smooth, concentric, funnel-shaped chamfer sloping inward at a 45-degree angle toward the 4.5mm center hole, acting as a visual and mechanical drop-guide for the central chronograph second hand. The model must be clean manifold geometry, ready for SLA resin 3D printing export as an STL file."
