So a week or two ago I got my order, including an item which was supposed to have a QR code embossed on it (to be colored in later). But the code isn't right: see attached picture. Note the "target" squares on the right, supposed to be squares within squares (as they are elsewhere) but instead have other stuff inside. And other imperfections in other places... In more careful inspection, it looks like these errors are there even on the 3D rendering provided in the Shapeways shop... but they aren't in my original! Any suggestions?
