There are a large number of programs you can use to design CNC projects and operate a CNC, but my favorite for both is Inventables' computer-aided-design (CAD) and computer-aided-machining (CAM) program Easel. It is super-simple to use, and it is constantly being improved to add more capabilities to it. For instance, they have recently added applications that can generate gears, generate inlays, and make puzzle pieces.
One of the things I really like about Easel is how easy it is to make, save, and share various projects. There are hundreds, and maybe thousands of projects available on their main project page at https://www.inventables.com/projects.
I have created quite a few projects, and plan to add more as time goes by. Here are the projects I currently have available for those who want to make one of my MWP designs:
