Interlocking Earth Puzzle

thingiverse

This 20-piece Earth puzzle puts your geography knowledge to the ultimate test! Based on a 20-sided icosahedron, each edge features a tab that seamlessly interlocks with any other edge on any other piece. The files are organized into four distinct groups: "N," "NE," "S," and "SE." Each group consists of five puzzle pieces. Pieces labeled "N" share a vertex located near the Bering Strait, roughly at the north pole. Meanwhile, pieces labeled "NE" all connect with an adjacent "N" piece along their edges. Similarly, pieces labeled "S" converge on a vertex situated near the south pole, while "SE" pieces join forces with neighboring "S" pieces along their edges. For convenience, separate files are provided for each individual piece, as well as comprehensive "Combined" files to print entire groups together at once. Printing from these "Combined" files yields the best results, though. The "Full Earth Print Ready" file contains all puzzle pieces in one convenient package – but be warned: a single error during printing can ruin the entire project. To achieve optimal results, we recommend printing with layer heights of .10 mm or less. This ensures that even the oceans' contours remain smooth and unobtrusive, allowing the overall design to shine through.
