MakeCrank

This app designs crank arms to your specifications using a leather cutter or 3D printer. Input dimensions, and it generates SVG (2D) or STL (3D) files. These files can be viewed and shared with other applications. The app automatically calculates the necessary balance weight size based on factors like balance weight outer diameter, mass on the crank pin side, 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 with other applications and can be shared directly with connected 3D printers and PCs. A credit card is shown for scale in the app's interface.
