Create crank arms with precise dimensions using a leather cutter or 3D printer. This tool calculates dimensions and generates SVG (2D) or STL (3D) files for your crank arm. The generated data is easily viewable and shareable with other applications.
Automatic balance weight sizing is included. The tool calculates the necessary weight size 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 integrates seamlessly with other applications and can be shared with 3D printers and connected PCs. A credit card overlay provides size comparison.
