So here's a little piece I found kind of interesting. It came as part of the packaging on one of my wife's sewing machines. When I look at the detail of this piece from a machinists point of view, I find it very detailed. Nice corner radii, but not sharp as those wouldn't be good from a stress standpoint is my guess. Yes, it's just a piece of injection molded plastic but it serves a purpose in the shipping of a very pricey sewing machine so it was/is worth the money from the manufacturers' point of view.
