Summary

Octagonal fillet gauges

Most fillet gauges are used to measure the curved corner of a rectangle (flat faces are at 90 degrees), but these fillet gauges are used to measure the curved corner of an octagon. (flat faces are at 135 degrees)

Markings indicate the radius of the curve in mm.

The SCAD files are included so you can easily resize/re-label/remix using OpenSCAD.

The "ngon" function code comes from the "Polygon areas.scad" example in OpenSCAD.
