MakeCrank

Crank Arm Design and Fabrication Tool

This tool enables you to create crank arms with specific dimensions using either a leather cutter or a 3D printer. It calculates the necessary parameters and generates either an SVG file for 2D designs or an STL file for 3D models of the crank arm.

Key Features:

• Automatic Calculation and Generation: The tool calculates the required dimensions based on your input and automatically generates the crank arm design in SVG or STL format.
• Balance Weight Calculation: It computes the size of the balance weight needed for the crank arm, taking into account the outer diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm material.
• Data Sharing and Display: The generated data can be viewed and shared with other applications. It is designed to work seamlessly with 3D printers and connected PCs, facilitating easy fabrication.
• Size Comparison: For reference, the design includes an underlaying square the size of a credit card.

Parameters:

• Crankshaft diameter (mm)
• Crank pin diameter (mm)
• Crank arm length (mm)
• Crank arm width (mm)
• Balance weight radius (mm)
• Thickness (mm)
