Looking for Compression Springs? Look no further.
 

This OpenSCAD script allows you to generate a wide variety of parametric compression springs with fully customizable geometry and configurations. Whether you need uniform pitch, variable pitch or dead coils, this script lets you design springs tailored to your specific needs. Perfect for prototyping, education and custom mechanical assemblies.
 

Click on Customize to open the generator.

🚀 Quick Start

1. Select Spring Dimensions

Define the key parameters for your spring:

• Length: Free length of the spring.
• Diameter: Outer diameter of the spring.
• Wire Diameter: Thickness of the spring wire.

2. Customize Your Coil

Configure your spring with versatile options:

• Coil Count & Pitch: Adjust active coils and pitch spread for uniform or variable spacing.
• Dead Coils: Set fixed ends with dead coils at the top and bottom.
• Midpoint & Spread: Fine-tune pitch transitions for custom compression characteristics.
• Profile Options: Choose between circular or rectangular (plastic) wire profiles.

3. Render and Export

Once customized, generate the spring and export it for slicing and printing. Enabling support and variable layer height is highly recommended. Click on Auto Orient to lay the spring flat. For filament, avoid brittle materials like PLA matte - I have printed all examples in PETG HF. After printing, careful to remove the support to avoid breaking the threads. And then enjoy!
