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

Generates SVG (2D) or STL (3D) crank arm files based on your specified values.

View and share the generated data with other applications.

Automatically calculates the required balance weight size.

Determines the balanced weight dimensions using the balance weight's outer diameter, the mass (g) on the crank pin side, and the crank arm density (g/cm³).

Computes the appropriate 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)
