Heptagon Spring Fidget

Heptagon Spring Fidget This is a fun and satisfying fidget toy inspired by the classic coil-spring toys — but with a heptagon-shaped twist. It can be stretched, compressed, or flipped around to relieve stress or simply pass the time, and it’s also great for demonstrating flexible 3D printing and fine tolerances. ✨ Features: Fully 3D printable in one piece (no supports required) Designed for smooth and consistent spring motion with a heptagon-shaped profile Works as both a tactile fidget toy and a unique desk decoration No supports or rafts needed Prints well with PLA, ABS, or PETG — but for the best visual effect, try a silk or shiny filament 🛠 Usage Tips: After printing, gently stretch the model to separate each coil If it doesn’t separate easily, it may be due to over-extrusion or insufficient cooling → Check your printer’s extrusion and cooling settings for best results When separating the parts, handle gently. Excessive force may cause breakage. 📄 File Naming Note: D = Maximum he
