Create precisely sized crank arms using a leather cutter or 3D printing technology.

Computes dimensions from your inputs and produces 2D (SVG) or 3D (STL) crank arm files.

The resulting designs can be viewed and shared with other applications.

Automatically calculates the required balance weight dimensions.

Uses the counterweight's outer diameter, crank pin side mass (grams), and crank arm density (g/cm³)

to determine the appropriate balancing weight size.

Parameters

・ Crankshaft diameter (mm)

・ Crank pin diameter (mm)

・ Crank arm length (mm)

・ Crank arm width (mm)

・ Balance weight radius (mm)

・ Thickness (mm)

View generated designs seamlessly through integrated applications,

or share directly with connected 3D printers and computer systems.
