The prompt

Create a functional, 3D-printable sock clip based as closely as possible on the uploaded reference image. The product is inspired by a traditional bobby pin (hairpin), but larger, with two long, gently wavy arms designed to hold a pair of socks together during machine washing. **Design specifications:** - The clip section must be exactly 70 mm long, excluding the hanging hook. - The two arms should have approximately 3 smooth, gentle waves along their length. - Both arms should follow matching wave patterns, like the reference image. - Leave approximately 8 mm of space between the two arms at their lower ends. - The arms should gradually come closer together toward the top, where they connect. - Both lower ends must be rounded and slightly bulb-shaped, with no sharp edges. - Add a large, smooth, classic J-shaped hanging hook at the top, matching the reference image. - The hook must be integrated into the clip as one continuous piece. - The hook opening should be large enough to hang on a standard laundry drying rack. - The overall design should be approximately 15 mm wide across the clip section, where practical. - Use smooth, rounded edges and a minimalist, elegant appearance. - The product should resemble a slightly oversized, wavy bobby pin with a hanging hook. **3D printing requirements:** - Create a single connected, watertight solid suitable for FDM 3D printing. - Avoid unnecessary details, unsupported overhangs, and extremely thin sections. - Design the arms to have some flexibility while maintaining sufficient grip on socks. - Make the hook sturdy enough for repeated use. - Use millimeters for all dimensions. - Make the model suitable for exporting as an STL file. **Important:** Follow the uploaded reference image as closely as possible. Do not redesign the clip into a conventional clothespin, spring clamp, or carabiner. Preserve the original wavy bobby-pin shape, rounded tips, wider lower opening, and simple curved hanging hook.
