Get Ready to Challenge Your Geography Skills with This 20-Piece Earth Puzzle! This puzzle is designed to put your geography knowledge to the test, featuring a 20-sided icosahedron as its base. Each edge of this unique shape has carefully placed holes for a pair of 3mm x 1mm cylindrical magnets that keep everything in place. The files are organized into four distinct groups: "N," "NE," "S," and "SE." Within each group, you'll find five puzzle pieces that share specific characteristics. Pieces labeled "N" all have a vertex located near the north pole, roughly at the Bering Strait. The "NE" pieces share an edge with their "N" counterparts, while those labeled "S" share a vertex near the south pole. Similarly, "SE" pieces all share an edge with an "S" piece. To make printing easier, separate files are provided for each individual piece, as well as combined files that allow you to print groups together. Printing the "Combined" files is recommended, as this approach ensures a seamless build process. However, if you do choose to use the "Full Earth Print Ready" file, which features all pieces together, be aware that an error during printing can compromise the entire project. When scaling the files, keep in mind that the holes designed for 3mm x 1mm cylindrical magnets may no longer be suitable once scaled. To achieve a smooth and even finish, it's recommended to print with layer heights of .10 mm or less.
