Golden Ratio Callipers

Golden Ratio Callipers

This design was prompted by Bob Cater in Wales.  He was describing the Visconti Divina Proportione fountain pen which comes with a lovely three legged calliper.

A similar calliper could be useful in product design courses so students can measure existing products and determine the proportions of their own designs.

The ZIP file is attached containing a PDF, Creo models and a dxf for laser cutting. Start by reading the PDF.


If you use this in your teaching please post feedback and examples.
