MakeCrank Rate : 4.3

Crafting custom crank arms to your exact specifications is now easier than ever, whether you're using a leather cutter or a 3D printer. Our tool calculates from your specified values and generates precise SVG files for 2D designs or STL files for 3D models of your crank arm, making it seamless to bring your project to life.

The generated data can be easily displayed and shared with other applications, ensuring you can collaborate or proceed with fabrication without hassle. Additionally, our tool automatically calculates the size of the balance weight, streamlining your design process. From the outside diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm material, we help you determine the perfect size for a balanced weight.

Key parameters you can specify include:

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

The generated data can be displayed in conjunction with other applications, allowing for seamless sharing with 3D printers and connected PCs. For size comparison, the underlaying square in our visuals represents a credit card, giving you a clear reference point.
