Create crank arms with precise dimensions using a leather cutter or 3D printer. This application calculates dimensions and generates SVG (2D) or STL (3D) files for your crank arm. Generated data is easily displayed and shared with other applications.
The application automatically calculates the necessary balance weight size. Input the balance weight's outer diameter (mm), mass (g) on the crank pin side, and the crank arm's density (g/cm³), and the application will determine the appropriate weight size for balance.
Parameters
- Crankshaft Diameter (mm)
- Crank Pin Diameter (mm)
- Crank Arm Length (mm)
- Crank Arm Width (mm)
- Balance Weight Radius (mm)
- Thickness (mm)
Generated data integrates seamlessly with other applications and can be shared directly with connected 3D printers and PCs. A credit card overlay provides a convenient size comparison.
