Create your own flexible 3D‑printed springs with this fully parametric spring generator. 

This model includes six spring styles, all generated from clean mathematical paths and extruded into a smooth, printable ribbon. Every spring is automatically oriented flat on the build plate for perfect, support‑free printing.

Included Spring Styles

• Rounded serpentine
• Sharp zig‑zag
• Smooth sine wave
• Double spring (two interleaved coils)
• Tapered spring (narrows toward the top)
• Conical spring (narrows at both ends)

Fully Adjustable Parameters

• Height (travel distance)
• Width (lateral excursion)
• Depth (extrusion thickness / bed contact)
• Wire thickness (soft vs stiff)
• Number of coils
• Curve smoothness ($fn)
• End caps (on/off)
• Cap thickness
• Cap overhang
• Taper ratio (for tapered / conical styles)

Print Recommendations

• TPU 95A for flexible springs
• PLA for rigid mechanical springs
• Print flat on the bed (orientation is automatic)
• No supports needed

• 3–4 walls for strength

   

Use Cases

• Soft bumpers
• Vibration dampers
• Toy mechanisms
• Experimental spring designs
• Engineering prototypes
• Press‑fit or bolted applications (with end caps)
