Looking to create custom crank arms? Whether you're using a leather cutter or a 3D printer, our tool has got you covered. Simply input the specified dimensions, and we'll generate an SVG (2D) or STL (3D) file of your crank arm. The generated data can be easily displayed and shared across various applications, making it super convenient for your projects.

Our tool goes the extra mile by automatically calculating the size of the balance weight. From the outside diameter of the balance weight, the mass (g) on the crank pin side, and the density (g/cm³) of the crank arm, we'll help you determine the perfect size for a well-balanced crank arm.

Key Parameters:

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

Once your crank arm data is generated, you can seamlessly display it in conjunction with other applications. Sharing your designs with 3D printers and connected PCs is a breeze. To give you a sense of scale, we've included an underlaying square the size of a credit card for easy comparison.
