The prompt
Create a realistic parametric 3D CAD model of a modern industrial safety helmet based closely on the reference image. Design: - White rounded construction helmet shell with a wide front visor. - Black central top rail with two yellow accent strips. - Black front rectangular camera housing with two circular cameras side by side. - Two large symmetrical lateral airbag housings around the temple/ear areas, inspired by the reference. - White rounded airbag covers with yellow structural supports and black mounting frames. - Model folded airbags inside both lateral housings. - Add internal gas inlet/nozzle and cylindrical cartridge mounting space. - Add realistic internal suspension straps and adjustable black chin strap with buckle. - All modules must be separate components mechanically attached to the helmet. Airbags: The airbags are stored folded inside the lateral housings. They are designed to deploy downward and around the sides/rear of the head during an impact. Keep them in the folded state in the CAD model. CAD: Create clean solid geometry with realistic wall thicknesses, fillets, mounting bosses and interfaces. Keep left/right airbag systems symmetrical. Separate the helmet shell, camera module, airbag housings, airbags, suspension and straps into distinct components. Use realistic proportions for an adult head (approximately 60 cm circumference). The final model must look like a manufacturable engineering concept and remain visually faithful to the reference image.
