MakeCrank

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

Generates 2D SVG or 3D STL files of the crank arm based on your specified parameters.

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

Automatically calculates the required balance weight size.

Determines the appropriate balance weight dimensions using the outer diameter, mass (g) on the crank pin side, and crank arm density (g/cm³).

Computes the counterweight size 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)

View generated data directly within compatible applications,

and share with connected 3D printers or computer systems.
