I just could not find a narwhal cookie cutter that pleased me. So I made a nice, saucy and cute one to grace the high seas (metaphor. cookies should only swim in milk).
One thing I have noticed about cookie cutters that are 3d printed is they are saving money on the cost of the cutter by making the cutters too shallow. A good sugar cookie that will keep its shape for decorating needs the dough to be at least .25" deep. If the cookie cutter is not at least .4" deep, it is going to be very difficult to cut a cookie efficiently, especially if doing a batch. please watch out for this when making your selections!
