fly-inspired clothespin 3d model

Create a functional 3D model of a clothespin inspired by a fly (housefly), optimized for FDM printing in PETG. The model must be a single-piece design (print-in-place) with a flexible living hinge replacing a metal spring. It must securely grip fabric. Dimensions: * Length: 70–90 mm * Opening gap: 15–25 mm * Hinge thickness: 2.5–3 mm Design: * Fly shape with large eyes, segmented body, and wings (decorative but thick enough to print) * Front section acts as gripping jaws * Add small internal ridges for better grip Constraints: * No supports required * Max overhang: 45–60° * Minimum wall thickness: 1.2 mm * Smooth opening/closing without breaking * Avoid fragile thin parts Optimized for PETG flexibility and durability. Focus on mechanical reliability over extreme detail. Output STL-ready model.
