The prompt
Prompt Create a precise engineering-style 3D model of a screw-on replacement cap for a swimming pool cover water bag. Specifications: Circular screw cap. Outside diameter approximately 60 mm. Overall height approximately 28 mm. Internal right-hand single-start coarse plastic thread. Thread major diameter 42 mm. Thread minor diameter 38.5 mm. Thread pitch 5.5 mm. Thread engagement length 20.5 mm. Thread profile should be rounded buttress-style plastic bottle thread, not a sharp V-thread. Top surface 5 mm thick. Outside surface with 8 deep vertical grip ribs equally spaced around the circumference. Slight fillets on all external edges. Flat internal sealing face suitable for adding a rubber O-ring. Designed for FDM 3D printing in PETG. Engineering dimensions should be prioritised over artistic appearance. Produce a watertight manifold mesh suitable for STL export.
