I designed the bridge based on the signature bridge of Bashkin Guitars, with some small modifications. I copied the bridge slot and pinhole layout from another student in my workshop. I've included the .STL 3D model of my bridge, as well as a 2D tracing of the shape in the photos.
You definitely don't need access to a CNC machine to make a nice bridge. I've found many discussions online about how to make bridges with hand tools and traditional routers. There are also many good books detailing the traditional process of building a guitar, including bridge construction. One book I found at my local library that helped me understand and install the bridge was Build Your Own Acoustic Guitar - by Jonathan Kinkead.
