Relay Guitar Platform
A 3D-printed electric guitar platform. One shared body, many distinct instruments. Build the guitar that fits how you play.
The Relay Guitar Platform is something I built as a community project. I am providing you the information and resources that are necessary to print and build yourself a professional quality instrument that's suitable for players of all levels. I'm providing the models and documentation free of charge in the hopes of attracting a community of makers who want to support each other so that we can experiment, explore, and grow together.
I don't want to give you the impression that building a guitar is an easy, or even inexpensive, process. Parts of the process can be pretty challenging, but I've done my best to minimize those challenges and set you up for success. In terms of cost, if you're looking for a budget starter guitar, you can buy a decent instrument for less than it'll cost you to build one. However, from my perspective, there's nothing quite as satisfying as creating something with your own hands that plays and sounds amazing. When I started working on this platform I was able to source the materials for roughly $250. Now, 6-months later, it's closer to $400 if you buy everything new, but you can save a lot of money if you scavenge the parts from old or broken instruments. How you get the parts is entirely up to you.

Voicings
