The prompt

Generate a single, seamless, rotationally symmetrical container liner designed for injection molding. Total height is 90mm. The main body is a cylinder with a constant outside diameter of 74.5mm and an ultra-thin wall thickness of 1.1mm. The bottom of the cylinder transitions into a smooth, fully filleted dome cap with a radius matching the cylinder. At the top opening, create a reinforced, rigid collar with a height of 10mm and a wall thickness of 2.5mm. The outside diameter of the top collar is 89.5mm to act as a wide overhang lip that rests over a 3.5-inch jar opening. Transition the 2.5mm thick top collar down into the 1.1mm thin body using a gradual, continuous internal chamfer taper to prevent stress concentrations. Export the final model as a clean, watertight parametric STEP file
