Body
The body is the foundation of the instrument. This is the most critical part to get right. I've given you a large safety net with this design so you can make a lot of mistakes and still end up with a great instrument, but the compromizes you make here will be compounded later.
All of the voices of the Relay Guitar Platform are designed to work with the same body model.

Two kilograms of filament are required for a complete body. See Print for why material choice matters. There are parts of the body that can be printed with less-expensive materials without compromizing the integrity of the build, but I prefer to use PET-CF (not PETG) because of the ease of use and material strength.
A flexible marine-grade epoxy that handles vibration and stress without cracking. I've tested alternatives and come back to this every time. If you need to make a substitution, look for a slow-curing, flexible epoxy, designed for use on plastic. It's expensive, but the volume of epoxy that you get here is enough to build 4 guitars.
