This opener was specifically dimensioned to hug the bottle for a longer lasting and better functioning opener. I wanted to print my own bottle opener but nearly all of the existing designs either use a coin or are of a flat like design. The flat design causes a stress increase at the point of opening that can be relieved by a curved design that covers more of the bottle cap and hugs the bottle. I tested it printing 5 perimeters with 50% honeycomb infill using ABS and I'm very happy with it.
