MakeCrank

This app designs crank arms to your specifications using a leather cutter or 3D printer. Input dimensions, and it generates SVG (2D) or STL (3D) files for use in other applications. It automatically calculates the size of the balance weight needed, based on factors like the balance weight's outer diameter, mass on the crank pin, and crank arm density (g/cm³).

Key Features:

• Customizable Dimensions: Specify crankshaft diameter, crank pin diameter, crank arm length, crank arm width, balance weight radius, and thickness (all in mm).
• Automatic Balance Weight Calculation: The app automatically determines the size of the counterweight needed for balance.
• File Generation: Creates SVG (for 2D cutting) and STL (for 3D printing) files.
• Data Sharing: Easily share generated designs with other applications and 3D printers.
• Visual Size Comparison: A credit card is overlaid for scale reference.

Version 0.5 (Updated Oct 9, 2022):

• Set a minimum density for balance weight calculations.

Previous Updates:

• 0.4: Added parameter limits.
• 0.3: Added support for D-cut designs; added automatic balance weight size calculation.
• 0.2: Added support for balance weights and circular designs.
• 0.1: Initial release.
