After using the scale for a while, I decided to give it a few new features: Paper-rivet lined hang-up holes and two index points for setting the dividers to the index span of 60 degrees. You don’t need the index points as you can just set to zero on 60 on the chord line, but the points are more convenient and a ensure a bit more accuracy. I’ve changed the template so these upgrades are now represented on the free template download. I’ve also added a couple of sentences to the pamphlet to describe the use of the index points. I’ve also added dotted cut lines to get the shape as shown.
