Create custom-sized crank arms using a leather cutter or 3D printer.
It calculates from your inputs and generates 2D (SVG) or 3D (STL) crank arm files.
You can view and share the generated data with other applications.
Automatically calculates the required balance weight size.
Based on the balance weight's outside diameter, the mass (g) on the crank pin side, and the crank arm material density (g/cm³),
it determines the size of a counterweight that achieves proper balance.
Parameters
・ Crankshaft diameter (mm)
・ Crank pin diameter (mm)
・ Crank arm length (mm)
・ Crank arm width (mm)
・ Balance weight radius (mm)
・ Thickness (mm)
Display the generated file directly in a linked application,
or share it with connected 3D printers and computers.
A credit card is shown in the underlying square for size reference.
