MakeCrank

Create crank arms to exact specifications using a leather cutter or 3D printer.

It calculates based on your inputs and generates a 2D SVG or 3D STL file of the crank arm.

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

Automatically calculates the required balance weight size.

Based on the outer diameter of the balance weight, the mass (g) on the crank pin side, and the crank arm density (g/cm³)

it determines the size of weight needed for proper balancing.

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 data directly within the linked application,

and share it with connected 3D printers or other PCs.

A credit card in the underlying square provides a size reference.
