I used Inventor and Fusion 360 to create a 3D Maze that will be cut out with the CNC router. The passes for the maze must be a half inch as well as the border. The maze is three fourths an inch tall. Here's a picture of it.

CNC Mill
I designed another widget that I will use the CNC mill's subtraction process to cut out. Here's what it looks like.
