Parametric Double Helical Gear Generator (STEP, Customizable, CNC & 3D Printing)

Description
This is a parametric double helical gear model generated using an automated CAD system.
Unlike fixed models, this gear is not a one-off design — it can be regenerated with different parameters.
Specifications of this model:
Module: [X]
Number of teeth: [X]
Helix angle: [X]° (5–45°)
Pressure angle: 20° (normal)
Gear type: Double helical / herringbone (continuous Sykes type, no center groove)
Standard: Based on involute gear geometry
Use cases:
High-load power transmission
Thrust-free parallel-shaft gear drives
CNC machinery
3D printing
Mechanical design prototyping

Why this matters:
Most models here are static.
This system allows you to generate exactly what you need.
Note:
A double helical (herringbone) gear joins two opposite-hand helical halves back-to-back, so the axial thrust of each side cancels out.
The module is the normal module; the transverse module is calculated internally as m / cos β.
