metal hairpin clip 3d model

A quad-based 3D model of a metal snap hairpin clip, based on simple mechanical curves and smooth industrial geometry. The outer border is thick and rounded, while two thin inner rails curve smoothly along the frame. Include a circular hinge base at the bottom. Topology must look clean and evenly spaced like a hand-made Blender model, with visible edge loops following the silhouette. Slightly beveled edges, no shading issues, no ngons, no stretched polygons. Output with clean geometry and optional wireframe preview.
