Preview — This is an early look at the Relay Guitar Platform. Content and specs may change before launch.

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.

Materials and Supplies

PET-CF Filament (×2 1-kilogram spools)SpecificFlexible
buy at Amazon·$66.00

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.

Alternative: PET-GF (glass fiber filled) is a valid alternative to PET-CF and may be less expensive. Both provide the dimensional stability and strength this build requires and can be used with each other in the same build. Do not use PLA or standard PETG — they can fail under string tension over time.
G/Flex 650 EpoxySpecific
buy at Amazon·$32.00

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.
