Google SketchUp is a tool used for designing anything you want and is fairly easy to use. You just click on the shape you want and it will pop up on your screen and if you click on the variety of tools and interact with the shape, you can resize it, change the color, and many other things.
I give this tool a 3 out of 5 because it took me a while to get used to using it.
you can find this tool here
