How do I customize this?

This is an OpenSCAD project. OpenSCAD is a script-based modeling software specifically created for projects like this that need to be customizable.

If you're new to the program, it may look strange at first, but most of the work is just typing values into a form or selecting customization options from a dropdown list. You do not need to know any programming or write a single line code to use OpenSCAD.

Once you've entered everything you need, you can export an STL file for printing. Here's a helpful video that walks through the entire process!

Parameters

• Coil Count - Sets how many coils the spring has. More coils will result in a more flexible spring.
• Weight - Sets how heavy the spring “wire” is. For best results, set this value to a multiple of your nozzle diameter.
• Thickness - Sets the overall thickness of the spring. A thicker spring will be less free to bend horizontally.
• Width - Sets how wide the spring coils are. A wider spring will be less free to bend forward and backward.
• Top Width - Adds an optional extended top to the spring.
• Top Height - Sets the height of the optional top of the spring. Use this to make the spring taller without adding coils.
• Bottom Width - Adds an optional extended bottom to the spring.
• Bottom Height - Sets the height of the optional bottom of the spring. Use this to make the spring taller without adding coils.
• Peg Width - Sets how wide (and tall) the attachment peg on the spring is.
• Peg Length - Sets how long the attachment peg on the spring is.

Printing

• Set perimeter count high enough for spring arms to be filled with perimeter lines
• Some configurations will require supports - most commonly when the peg height is less that the overall spring thickness.

Update

You can now create a customized spring insert tool. This will only work if only one end of the spring has a wide ledge.
