Stackable Stencil

I had and idea for a stackable stencil that could be printed on a 3d printer. Unfortunately I don\'t have one yet (please help me w/ that makerbot!!). This is also my first attempt at modeling in Blender so take it easy on me. I thought it would be handy to create a stencil that could be anything you wanted it to be. You should be able to scale this to as large as your build platform. Hopefully there won\'t be issues with warping, it may require a heated platform. Sadly I can\'t test it mys
