Low Poly Spheres: Octahedron

Low Poly Spheres: Low-poly, high-fun!

Low Poly Spheres is a series 3D printable models of polyhedra that look like low-poly spheres. You may remember from math class that polyhedra are solid 3D shapes with flat polygonal faces, straight edges, and sharp corners or vertices. Low Poly Spheres are fun to make and display. You can print them in different colors and sizes, and use them as decorations, toys, or educational tools. Low Poly Spheres are a fun way to enjoy 3D printing and mathematics. They are simple, yet beautiful and fascinating. 

Octahedron - Fun Facts

An octahedron is a three-dimensional shape that has eight faces, all of which are equilateral triangles. It is one of the five Platonic solids, which are shapes that have the same number of faces, edges, and vertices meeting at each corner. The word octahedron comes from the Greek words for eight (octa) and face (hedron). Some fun facts about octahedrons are:

• An octahedron can be made by joining two square pyramids at their bases
• An octahedron is the dual of a cube, which means that if you connect the centers of the faces of a cube, you get an octahedron, and vice versa.
• An octahedron has 24 symmetries, which means that there are 24 ways to rotate or reflect it without changing its shape.
• An octahedron is related to the golden ratio, which is a special number that appears in nature, art, and mathematics. The ratio of the length of an edge to the radius of a circumscribed sphere is equal to the golden ratio.
• An octahedron is a common shape for crystals, such as diamonds and fluorite.
