Create custom-sized crank arms using a leather cutter or 3D printer.

Generates 2D SVG or 3D STL crank arm designs from your specified parameters.

The output data can be viewed and shared with other applications.

Automatically calculates balance weight dimensions.

Based on the balance weight's outer diameter, the crank pin side mass (g), and the crank arm density (g/cm³)

Computes the required counterweight size for optimal balance.

Parameters

・ Crankshaft diameter (mm)

・ Crank pin diameter (mm)

・ Crank arm length (mm)

・ Crank arm width (mm)

・ Balance weight radius (mm)

・ Thickness (mm)

Display generated designs directly through your application,

Share with 3D printers and connected computers.
