Building parametric guitar fretboards in Onshape - including Fanned Frets!!

Fretboards (indeed guitars) are beautiful things combining math and music and aesthetics... The pattern that drives the position of the frets is simple enough: position from nut = scaleLength - (scaleLength / (2 ^ (i / 12)))
But how do you implement this in CAD?

Onshape makes it easy, and by adding parametrics, configurations, decals, expressions to capture logic, and more... it's a really nice experience!

But there's more in this video... Fanned Fret guitars are fascinating things, and the fretboard looks super cool. Come with me on a journey to examine all this.

This is exactly what I was looking for, and the fact that it is easily accessible and configurable is awesome! Thank you so much!

I did fiddle with it a bit since I recorded the video (fixed a few deliberate errors, etc) but I also enhanced it more rigorously handle specifications such as string width at the nut/bridge.

If you do copy it and experiment with it (and like it!) then please feel free to tell people where you found it....
