This application designs crank arms of custom dimensions using a leather cutter or 3D printer. Input parameters determine the output, generating 2D (SVG) or 3D (STL) models. The generated data is easily viewable and shareable with other applications. Automatic balance weight calculation is included. Calculations are based on balance weight outer diameter, crank pin side mass (g), and crank arm density (g/cm³).
Input Parameters:
- Crankshaft Diameter (mm)
- Crank Pin Diameter (mm)
- Crank Arm Length (mm)
- Crank Arm Width (mm)
- Balance Weight Radius (mm)
- Thickness (mm)
The generated data integrates seamlessly with various applications and can be shared directly with connected 3D printers and PCs. A credit card is shown for scale in the application interface.
