I attempted to build the original design by MyE3D, but I had a lot of difficulty with the fret installation.  The force required to install the frets kept damaging the neck beyond usability, and I gave up on the project for a bit.  I wanted to use the design because of the traditional body shape that could fit in my print bed in one piece, so I redesigned the fretboard to print directly including 3D printed frets, and they work!

In addition to the 3D print, I purchased a set of ukulele strings and 4 machine head guitar tuners.

Here's a YouTube mini series I made about the build: https://youtube.com/playlist?list=PLHcXUO0tVZqd1lQU6LbcZKJ0y5CJ6VVjr
