Summary

This is a simple tool is used to crown the tops of musical instrument frets after they've been leveled. Crowning rounds over the top surface to eliminate the flat tops that were produced when the fret was leveled. This simple tool was created by Dan Thompson from the Guns and Guitars YouTube channel and he gave me permission to upload this design to Thingiverse. I designed this version to use one inch wide strips of sandpaper which can be cut from full sheets of sandpaper, or the strips can be cut from one inch wide sanding belts. Dan demonstrates how to use the fret crowning tool in a video.
