MakeCrank

Crank Arm Design and Fabrication Tool

Are you looking to create custom crank arms with precision? Our innovative tool allows you to design crank arms of specified dimensions using either a leather cutter or a 3D printer. Here's how it works:

Key Features

• Design and Calculate: Input your desired dimensions, and our tool calculates and generates SVG (2D) or STL (3D) files of the crank arm. This makes it easy to visualize and refine your design before production.
• Automatic Balance Weight Calculation: The tool automatically calculates the size of the balance weight based on the outside diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm material.
• Seamless Integration and Sharing: The generated data can be displayed and shared with other applications, making it easy to collaborate or send your designs directly to a 3D printer or PC.

Parameters

To ensure your crank arm meets your exact specifications, you can input the following parameters:

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

Visualization and Comparison

For a clear understanding of the size, the generated data is displayed alongside a credit card image, providing a practical size comparison.

What's New in Version 0.5

Last updated on Oct 9, 2022

• Version 0.5: Added a minimum density setting for balance weight calculations.
• Version 0.4: Introduced parameter restrictions to enhance design accuracy.
• Version 0.3: Added support for D-cut designs and automatic calculation of balance weight size.
• Version 0.2: Included support for balance weights and circular designs.
• Version 0.1: Initial release.

With our tool, you can easily design, calculate, and fabricate crank arms tailored to your needs, ensuring optimal performance and balance. Whether you're using a leather cutter or a 3D printer, our tool streamlines the process, making it accessible and efficient.
