The prompt
Create a parametric 3D CAD model of a Universal Auto-Lock Trash Bag Ring V2. Core concept: An adjustable, rounded-rectangle ring that fits around the upper rim of an existing household trash bin. It secures the folded edge of the trash bag from the inside. The product must remain a complete ring assembly, not a set of independent clips. Initial dimensions * Outer dimensions: 280 × 280 mm, adjustable. * Rail width: 18 mm. * Rail height: 12 mm. * Corner module length: 42 mm. * Four internal grip modules. * Rounded corners and smooth edges. Create each component separately: 1. Main frame: Four structural rails and four corner housings. 2. Adjustment mechanism: Telescoping sliding joints that allow the ring dimensions to change and lock securely. 3. Grip modules: Four inward-facing clamps distributed around the ring. 4. Soft grip pads: Replaceable TPE or silicone pads to grip the bag without cutting it. 5. Locking mechanism: Mechanical locking features to prevent accidental movement. 6. Quick-release mechanism: A recessed release control for removing the ring and replacing the bag easily. Assembly requirements * Show how every component connects. * Provide an exploded assembly view. * Provide an assembled isometric view. * Provide top, side, and sectional views. * Keep the locking mechanism inside the bin rim where possible. * Minimize the number of parts. * Design rigid components for potential PP or ABS manufacturing and soft pads for TPE or silicone. Deliverables * Editable parametric CAD model. * Separate part files. * Assembly file. * STEP export for CAD editing. * STL exports for 3D printing. * Dimensioned engineering drawings. Important: This is a prototype concept. Do not claim universal compatibility or production readiness. The adjustment joints, locking mechanism, clearances, grip force, lid clearance, durability, and load retention must be tested and refined before manufacturing.
