MakeCrank

Create custom-sized crank arms using a leather cutter or 3D printer.

Generates SVG (2D) or STL (3D) crank arm models based on your specified parameters.

The resulting data can be viewed and shared with other applications.

Automatically calculates the required balance weight size.

Determines the weight size needed for balance using the balance weight's outer diameter, the mass (g) on the crank pin side, and the crank arm's density (g/cm³).

Calculates the counterweight dimensions to achieve proper balance.

Parameters

・ Crankshaft diameter (mm)

・ Crank pin diameter (mm)

・ Crank arm length (mm)

・ Crank arm width (mm)

・ Balance weight radius (mm)

・ Thickness (mm)

Displays the generated data through integrated applications,

enabling sharing with connected 3D printers and computers.
