MakeCrank

Creating crank arms with precise dimensions can be achieved using either a leather cutter or a 3D printer. Our application simplifies this process by calculating the necessary dimensions and generating either an SVG file for 2D designs or an STL file for 3D models of the crank arm.

Once the crank arm design is generated, the data can be seamlessly displayed and shared with other applications, ensuring you can easily transfer your work to a 3D printer or a PC connected to it. The application also automatically calculates the size of the balance weight, making the process more efficient.

To determine the balance weight size, the application takes into account the outside diameter of the balance weight, the mass on the crank pin side (measured in grams), and the density of the crank arm material (measured in grams per cubic centimeter).

Parameters

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

The generated data is displayed in conjunction with the application, allowing for easy sharing with 3D printers and connected PCs. To help with size comparison, an underlaying square representing a credit card is included in the visual representation.
