MakeCrank

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 the crank arm based on user-specified parameters. Generated data can be viewed and shared with other applications.

The application automatically calculates the required balance weight size. This calculation uses the balance weight's outer diameter, the 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 is displayed within the application and can be shared with 3D printers and connected PCs. A credit card overlay provides size comparison.
