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 an SVG (2D) or STL (3D) file of the crank arm. This ensures that your design is accurate and ready for production.
• Balance Weight Calculation: 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.
• Compatibility and Sharing: The generated data can be displayed and shared with other applications, making it easy to transfer your designs to 3D printers or PCs connected to them.
• Size Reference: The underlaying square in the design is the size of a credit card, providing a clear reference for scale.

Parameters

To create your custom crank arm, you'll need to specify the following parameters:

• 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
