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! (Update added on 2025.08.04)
Now you can customize your own version with any dimensions you like.

No need to wait for new uploads — create your desired size instantly!

The "Sheet Thickness (height per coil)" parameter is currently unstable and may not work as expected.

⚠ Note: Parametric generation on MakerWorld still seems unstable, so errors can happen in any version.

If you need a specific size or shape, feel free to let me know — I'm happy to add it!
