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
