Creating crank arms with precise dimensions is now easier than ever, thanks to advanced tools like leather cutters and 3D printers. Our innovative software allows you to calculate and generate detailed 2D SVG or 3D STL files of your crank arms based on your specified dimensions. This means you can visualize, share, and even print your designs with ease.

One of the standout features of our tool is the automatic calculation of the balance weight size. By inputting the outside diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm material, our software calculates the perfect size of the weight needed to achieve balance. This ensures your crank arms are not only functional but also optimized for performance.

Key Parameters for Crank Arm Design

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

The generated data can be seamlessly integrated with other applications, allowing you to display and share your designs. Whether you're connecting to a 3D printer or a PC, our software ensures smooth data transfer and compatibility.
