Crank Arm Design and Manufacturing Tool

Crafting custom crank arms with precise dimensions is now more accessible than ever, thanks to our versatile tool that supports both leather cutters and 3D printers. This application calculates and generates detailed designs for crank arms based on your specified parameters, producing either SVG files for 2D cutting or STL files for 3D printing.

Key Features

• Automated Design Generation: Input your desired dimensions, and the tool calculates and creates SVG or STL files of the crank arm design.
• Balance Weight Calculation: The application automatically calculates the size of the balance weight required for your crank arm. It uses the outer diameter of the balance weight, the mass on the crank pin side (in grams), and the density of the crank arm material (in g/cm³) to determine the appropriate balancing weight.
• Compatibility and Sharing: The generated data can be seamlessly integrated and shared with other applications. It's fully compatible with 3D printers and PCs connected to them, making it easy to bring your designs to life.
• Size Reference: For a practical size comparison, the design includes an underlaying square the size of a credit card.

Parameters

To tailor your crank arm design, you'll need to specify the following:

• Crankshaft Diameter (mm)
• Crank Pin Diameter (mm)
• Crank Arm Length (mm)
• Crank Arm Width (mm)
• Balance Weight Radius (mm)
• Thickness (mm)

What's New in Version 0.5

Last updated on Oct 9, 2022

• Version 0.5: Now includes a minimum density setting for balance weight calculations.
• Version 0.4: Added parameter restrictions to enhance accuracy and usability.
• Version 0.3: Supports D-cut designs and automatically calculates balance weight sizes.
• Version 0.2: Introduced balance weight and circular design capabilities.
• Version 0.1: Initial release.

With these enhancements, our tool continues to evolve, ensuring that you can design and manufacture crank arms that meet your exact specifications with ease and precision.
