I have been following this for a long time. He makes the STL files public, do what you like with then but STL files are really only good for 3D printing. He makes money by selling metal CNC'd version of the same parts. So you can build a plastic version of the arm for the cost of the plastic (and motors and bearings)
If you want to make your own CNC'd metal version, you could reverse engineer the STL files. The only parts that need to be redrawn are the bearing pockets. It is easy to reverse-engineer STL files. I am doing this right now for an unrelated project in another open window with Fusion360. What software to use to control the arm depends 100% on what you want the arm to do. With robot arms, there are several classes of things to do. All of the interesting things can not be pre-scripted but use sensors to "see" the world that the robot interacts with.
