Here’s how I designed a shell inlay for a guitar headstock using Fusion 360, and cut the inlay using my CNC router.
Part 1 – Design in Fusion 360
Part 2 – Cutting Shell Material

Fusion 360 Project File
Here is the Fusion 360 project file that I used for this design. It is set up specifically for my machine and cutting tools so I make no guarantees that it will work for you, but you are welcome to use it at your own risk.
