Yeah, that's cool as hell, isn't it? The body is mostly done. The only thing left is the fretboard.

I would like to point out what makes the construction of this guitar so unique:

That's a side view of the entire guitar. Because of the geometry of tune-o-matic bridges, the neck must be set back from the body at about a three degree angle. This guitar also has a tilted headstock, making this a weird compound angle construction that I really can't figure out how to do in wood. This is how real Gibson Firebirds are made. It's a truly bizarre design that lends itself to very thin guitars.

Speaking of, this is exactly as thin as you can make a guitar. There are a few constraints on this, most notably the depth of the pickup selector switch, and the depth of the quarter inch jack. This design is within thousandths of an inch of the limits of those two parts. It's actually too thin in places, but there are ways to work around that.

So, this is one gigantic monolithic print with 'wings' glued onto the body. How am I attaching the body? With dowels:

There are quarter inch holes on each side of that joint. Epoxy a dowel in one side, apply some glue and clamps, and everything should fit together. This isn't how the real (wooden) guitars are made - that's some sort of V-groove mortise thingy. That's a smart idea - it's self-aligning and great for production, but I want to make this easy on myself.

Also note the control cavity and hole to the stop tailpiece. Gotta ground that shit, yo.

The only thing left is the fretboard. And, you know, building the printer that can make this thing.
