Circle Spring Coil Fidget

This is a fun and satisfying fidget toy inspired by the classic coil spring toy. The "Circle Spring Coil Fidget" can be stretched, compressed, or flipped around to relieve stress or simply pass the time. It's also a great print to demonstrate flexible 3D printing and tolerances.   Features: Fully 3D printable in one piece (no supports required) Designed for smooth and consistent spring motion Works as a tactile fidget toy or a simple desktop decoration No supports or rafts needed It prints well with PLA, ABS, or PETG — but for the best visual effect, I recommend using silk filament.   Usage Tips:After printing, gently stretch the model to separate each coil.If it doesn’t separate easily, it’s likely due to over-extrusion or insufficient cooling.In that case, we recommend checking and calibrating your printer settings related to extrusion and cooling.   Note on file naming:- w = width (outer diameter in mm)- h = height (in mm)Example: circle_spring_fidget_w50h20 → 50 mm diameter, 20 mm height ⚙ Parametric Version Available on Maker World!Customize any size instantly with the parametric model — no need for separate uploads.(Note: “Sheet Thickness” parameter may be unstable.)   If you need a specific size or shape, feel free to let me know — I'm happy to add it!
