Hint G3 - Strong 2-D shapes Designing and building your own Geomag models is great fun, but it takes a bit of practice to build strong models.
When working in 2 dimensions (2-D), we would suggest building shapes made up from triangles whenever possible, as shown in the photo.
Triangles add strength, because they are a "rigid" shape, unlike four-sided shapes, which can change configuration. |  |
