Square Spring Coil Fidget

slThis is a fun and satisfying fidget toy inspired by the classic classic coil-spring toys, designed with a square shape. The "Square 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 with square coils 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 dimension in mm) H = height (in mm) R = corner radius (in mm)Example: Square_SpringFidget_W30H50R5 → 30 mm width, 50 mm height, 5 mm corner radius   ⚙ Parametric Version Available on Maker World!
