Bore Length, Tone Holes, and Tenons!

This was probably the easiest part of the project - getting approximate measurements for the length of the body, tone hole placement, and tenon/socket dimensions. I’m a little worried I might’ve made a mistake by placing the tenons on top of the extension instead of incorporating it into the tubing, so I’ll try to print out the low Eb extension to test if it’s way flatter than it should be.
