Sphere Bottle Opener

The first item I designed from scratch. Pictures show personalized shell, but the attached shell file does not have text on the top. Scale up to 10x. For the insert, use 100% in-fill to make it strong. The coin slot fits coins 19mm in diameter and 1.9mm thick. Make adjustments to both insert and shell to fit coins of different size. Add a few drops of super glue to hold the two pieces together.
