I used three different types of components to build the basic shape of the guitar: 3d-printed parts, 20*20 VSlot profiles and plywood.

My printer (Creality CR10S4) has build volume of 40*40*40cm. Beeing able to print the shape of a guitar body was the main reason I went for this big printer.

I used vslots to make a stable core to take all the string tension - 3d-printed parts just would deform over time.

The back and the top of the body are just plywood, cutout with a cnc router. This hollowbody-sandwich-design is simple, has plenty of room inside for the electronic parts. I went for a telecaster shape, because it's simple and big too.
