Creating crank arms with precise dimensions using a leather cutter or 3D printer is now easier than ever with our advanced tool. This tool calculates the necessary dimensions from your specified values and generates either an SVG file for 2D cutting or an STL file for 3D printing of the crank arm.

The generated data can be seamlessly displayed and shared across various applications, ensuring you can easily collaborate or proceed with production. One of the standout features is the automatic calculation of the balance weight size, which is crucial for the performance and efficiency of the crank arm.

To calculate the size of the balance weight, the tool takes into account the outside diameter of the balance weight, the mass (in grams) on the crank pin side, and the density (in grams per cubic centimeter) of the crank arm material. This ensures that you can achieve perfect balance with precision.

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 can be displayed in conjunction with other applications and shared with 3D printers and connected PCs. For size comparison, the underlaying square in the visual representation is the size of a credit card.
