Prompt
Create a fully parametric OpenSCAD model of a hydraulic rod U-cup seal according to GOST 14896-84. General requirements: - Output only valid OpenSCAD code. - The model must be fully parametric. - The seal must be created using a 2D profile and rotate_extrude(). - Do NOT approximate the seal using cylinders and boolean subtraction. - The profile must be built from an accurate polygon with rounded corners. - Use helper functions to generate circular arcs. - All dimensions are in millimeters. Main dimensions: Rod diameter (ID): 90 mm Outside diameter (OD): 115 mm Overall height: 15 mm Seal type: Single acting hydraulic U-cup rod seal made from polyurethane (TPU 95A equivalent). Profile requirements: The profile must follow the standard GOST 14896-84 geometry. The profile contains: - flat bottom - vertical outside wall - outer chamfer 45° - rounded transitions - U-shaped inner cavity - flexible sealing lip - secondary support lip - inner sealing edge touching the rod - outer supp
