Guitar Fretboard Radius Gauge Tool

The original design is neat (particularly allowing for measurement over strings at both the top and bottom of the neck).

A Fretboard radius measurement is arrived at by extending the arc of the fretboard to form an imaginary circle around the neck. The radius of this circle is the fretboard's stated radius measurement.

The original design was based on the diameter of the imaginary circle instead of the radius. For this remix I have shaved the arcs on each edge to match the intended radius displayed.
