Volex Labs / Forge / Gear rack generator — text to CAD.

Gear rack generator — text to CAD.

Describe the rack — module, length, tooth height, pressure angle and mounting section — and Volex Forge lays out the straight involute teeth and returns a manufacturable STEP, STL or DXF that meshes with a pinion of the same module.

No tooth-spacing maths, no CAD seat. The teeth are generated to standard involute form at the correct pitch and checked before download, so the rack and pinion run smoothly.

Frequently asked

Will it mesh with my pinion?
Yes, as long as the pinion is the same module and pressure angle. Generate the matching pinion with the spur gear generator for a guaranteed pair.
Can I get mounting holes?
Yes — ask for holes at a given spacing along the back of the rack and they appear in the model, sized to your fastener.
What does a rack cost?
Forge is free to try; individual parts are from £2.99. You only pay when you download a file you want.
Which format should I use?
STEP for CAD and CNC, STL for 3D printing, DXF for the 2D tooth profile for laser or waterjet.
