XymuActive：Hand-Drawn Non-Circular Gear Design Tool

Easily design non-circular gears from hand-drawn closed curves. Visualize your gears and export them in STL or STEP formats.
*Please verify gear interference yourself.

Center Distance (mm): 40.0Size is automatically adjusted to this distance.

Number of Teeth: 30More teeth results in smaller individual teeth.

Tooth Height Ratio: 0.80Reduce if interference occurs (0.6-0.8 recommended).

Clearance (mm): 0.20Increasing this value makes teeth thinner.

Axle Hole Radius (mm): 4.15The white hole on screen will also change.
Ensure it does not exceed the gear outline.

Root Shaft Radius (mm): 3.95Thickness of the shaft on the hub (slightly smaller than the hole!). STL only.

Gear Thickness (mm): 5.0Thickness for 3D printing.

STL/STEP Export (Beta Price: $0)
