Some time back, we posted about [Gavin]’s laser-cut/3D printed Dymaxion Globe — if you haven’t read about it yet, you should check it out. [noniq] loved the idea, and like a true hacker, built and shared an improved Foldable Dymaxion Globe. It can snap together to form an icosahedron globe, or it can be laid flat to form a map.

Like the original, [noniq]’s version is laser cut and engraved, and uses some 3D printed parts. But it does away with the fasteners (that’s 60 pairs of nuts and bolts), and instead uses neodymium magnets to make all the triangle pieces snap together to form the icosahedron globe. The hinges are simply some pieces of gaffer-tape.

This design improvement creates a cleaner globe and also addresses some of the concerns posted in the comments of the earlier build. The design files are available for download on [noniq]’s blog — you need to 3D print some magnet holders and stopper plates, and laser cut the 20 triangle tiles. The stopper plates help ensure that the angle between tiles when it is put together is limited to 138 degrees, making it easier to assemble the globe.

Check out the video after the break to hear the satisfying “thunk” of neodymium magnets snapping together.
