Triangle Spring Coil Fidget

This is a fun and satisfying fidget toy inspired by classic coil-spring toys, designed with a triangular shape. The "Triangle 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 triangular 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: D = circumdiameter (diameter of the circumscribed circle in mm) H = height (in mm) Example: Triangle_SpringFidget_D30H50 → 30 mm circumdiameter, 50 mm height   ⚙ Parametric Version Available on Maker World!
