Crank Arm Design and Fabrication Tool

Are you looking to create custom crank arms with precise dimensions? Our innovative tool allows you to design crank arms using either a leather cutter or a 3D printer, ensuring you get exactly what you need for your project.

Key Features

• Custom Dimensions: Input your desired crankshaft diameter, crank pin diameter, crank arm length, crank arm width, balance weight radius, and thickness. Our tool calculates and generates the perfect crank arm design based on these parameters.
• Automatic Balance Weight Calculation: From the outside diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm, our tool automatically calculates the size of the weight needed to achieve perfect balance.
• SVG and STL Generation: Whether you need a 2D SVG file for a leather cutter or a 3D STL file for a 3D printer, our tool can generate the appropriate file format for your needs.
• Data Sharing and Display: The generated data can be easily displayed and shared with other applications, making it seamless to transfer your designs to a 3D printer or PC.
• Size Comparison: For a clear understanding of the size, the design includes an underlaying square the size of a credit card for easy comparison.

How to Use

1. Input Parameters: Enter the crankshaft diameter, crank pin diameter, crank arm length, crank arm width, balance weight radius, and thickness.
2. Generate Design: Our tool will calculate the necessary balance weight and generate an SVG or STL file based on your specifications.
3. Review and Share: View the generated design, complete with a credit card-sized square for size reference. Share the file with your 3D printer or other applications as needed.
