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

This tool calculates dimensions and generates SVG (2D) or STL (3D) files for crank arms. Generated data can be viewed and shared with other applications. It automatically calculates the size of the balance weight based on the balance weight's outer diameter, mass (g) on the crank pin side, and the crank arm's density (g/cm³).

Parameters:

• Crankshaft Diameter (mm)
• Crank Pin Diameter (mm)
• Crank Arm Length (mm)
• Crank Arm Width (mm)
• Balance Weight Radius (mm)
• Thickness (mm)

Generated data can be displayed and shared with connected 3D printers and PCs. A credit card is shown for size comparison.
