MakeCrank

Are you looking to craft crank arms with precision and ease? Whether you're using a leather cutter or a 3D printer, our innovative tool makes it simple to create crank arms of specified dimensions. Not only does it calculate the necessary measurements from your input values, but it also generates both SVG (2D) and STL (3D) files of your crank arm design, making it easy to visualize and share your work across various applications.

One of the standout features of our tool is its ability to automatically calculate the size of the balance weight. By inputting the outside diameter of the balance weight, the mass on the crank pin side in grams, and the density of the crank arm material in grams per cubic centimeter, you can determine the perfect size for a balanced weight. This ensures your crank arms are not only custom-made but also perfectly balanced for optimal performance.

Key Parameters for Customization

• Crankshaft diameter (mm)
• Crank pin diameter (mm)
• Crank arm length (mm)
• Crank arm width (mm)
• Balance weight radius (mm)
• Thickness (mm)

Once you've entered these parameters, the generated data can be seamlessly displayed and shared with applications linked to 3D printers and connected PCs. For a clear size comparison, the underlaying square in the display is sized to that of a credit card.
