If you own a 3D printer or laser cutter, chances are you've seen the famous cat walk toy. It's an example of a 3D printed object that actually walks on its own. The reason this works is because the legs are made of two different materials: one leg is hollow and stiff, while the other is solid and flexible. The same principle applies to building cat walks on your CNC router
The following steps will show you how I turned a cat into a walking machine, using a CNC router and a 3D printed head.
