Star-shape with arbitrary thickness and number of points. Depending on the dimensions, you'll either get one pyramid-like shape for every point of the star, or flatters (pancake-like shapes) for either side of the star. The latter is the quickest and easiest way, but thin stars with long points look the best. To obtain this one: use a large height, large inner radius and a low amount of points. The given parameters will work for this.
