Application Description

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

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

The generated designs can be viewed and shared in other applications.

Automatically calculates the required balance weight size.

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

it computes the size of the weight needed for 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.

Designs can be shared with connected 3D printers and computers.
