The Diamant Card Holder should be a quick print because I used "Vase mode" (a.k.a. "Spiralize Outer Contour") and it makes the walls just as thick as your nozzle. Let me be clear, only the Card Holder should be printed this way. Everything else should have that feature turned OFF and be printed in the traditional way.
