Guitar fretboard radius guages
thingiverse
A simple parametrized radius guage model (mainly for guitar fretboards, but I guess you could use it for other stuff, too). The Fusion 360 model uses the awesome ParametricText plugin from https://apps.autodesk.com/FUSION/en/Detail/Index?id=2114937992453312456 but you could just edit the text yourself, too.
