Coil Spring Generator

Generate a STEP file of a coil spring by specifying wire diameter, outer diameter, number of turns, and pitch.

Wire Diameter (d)

Wire thickness (0.5–10 mm)

Outer Diameter (Do)

Coil outer diameter (≥ 3× wire diameter, 3–200 mm)

Turns (N)

turns

Total number of coils (3–50, in 0.5 increments)

Pitch (p)

Distance between adjacent coil centers (≥ wire diameter, 0.5–100 mm)

End Coil Shape

Generate with closed ends

Checked: end coils are flattened (closed end)

Inner Diameter (Di)	6.00 mm
Coil Height (H)	10.00 mm
