![]() Instructors in any class using this activity should be forewarned that it is normal for students to become addicted to making business card cube structures.įor our final mathematical paper folding project of December, we assembled a Level 1 Menger Sponge model: Our level 1 Menger Sponge, built out of 120 business cards. In his book Project Origami, Thomas Hull gives instructions for folding models of portions of the Menger Sponge out of business cards. ![]() If you haven’t see those other things then this is a good opportunity to spend some quality time on Wikipedia. The Menger Sponge is a three-dimensional fractal curve if you have seen the Cantor Set (in one dimension) or the Sierpinski Carpet (in two dimensions), the Menger Sponge will look familiar to you. Thank you to Arif Babul (Physics & Astronomy) and Duncan Johannessen (Earth & Ocean Sciences) for the donations! Author Jane Butterfield Posted on DecemFormat Video Categories Origami Tags origami Leave a comment on Miura fold Menger sponge I will also add some examples made from geological survey maps, donated by a colleague from Earth & Ocean Sciences, because the Miura fold is also excellent for storing maps. I will update the Elliot Building displays soon, to include this space-themed example. In this video, you can see me demonstrating the two-points-of-contact folding and unfolding that the Miura fold provides: Click on the picture to watch the video. Because of this space connection I asked a colleague from Physics & Astronomy to donate something more space-related for me to fold, to replace the math research poster I had originally used for our display. Since our first assembly of the display, I have made several more!Īstrophysicist Koryo Miura developed this fold as a way of packing things such as solar panels flat, so that they could be very easily opened (and closed) in space. You can see some examples of this fold in the Elliot Building origami display ( here is a link to my post about that). It is harder to properly three-colour the triakis icosahedron, though! For the triakis octahedron and the triakis icosahedron, three colours suffice (the triakis icosahedron pictured below is properly three-coloured).An icosahedron has 20 faces, each of which is replaced by a trio of Sonobe units, and each unit participates in two faces, so you need 30 pieces of paper.The “cube” is actually a “triakis tetrahedron”, so it’s not as special as it seems! This might take some drawing to work out you might find it helpful to imagine what is left over if you slice each vertex off of a cube.You’ll need at least three colours for any of these models, because Sonobe units lock together in trios. ![]() How many faces has a cube got? Second way: each triple of Sonobe modules is going to form the corner of a cube how many corners is each module involved in, and how many corners has a cube got? There are at least two ways to count it! First way: each Sonobe module is going to end up with its square inner bit being the face of a cube. You can also use the digital papers for your digital and handmade craft projects.Assembly instructions for triakis octahedron (I didn’t print these): Hints and answers to my questions: in squares that you can print in 250 different colors. If you like paper with beautiful printed patterns, I created Digital Paper Packs where you can find beautiful Japanese patterns, floral patterns, geometric patterns, tropical patterns etc. For almost all of my models, you can use the plain "kami" origami paper (15x15 cm with a color side and a white side). You can get a lot of different types of origami paper from sites like Origami Shop. ![]() To create beautiful origami mosaics, try my easy origami pixels.Īnd if you like modular origami, building with Lego bricks or playing Minecraft, you definitely need to try my new origami cubes!
