Manipulative snap-together sprues to create polygons, polyhedra, molecules etc

thingiverse

Originally designed to demonstrate the relationship between angle measurements and side lengths in triangles and polygons, these educational tools offer versatility through their ability to create polygons with unique angles and side lengths. By employing them correctly, protractors can be easily used for measurement purposes. In an effort to enhance the learning experience, I crafted connecting objects featuring evenly spaced rings and vertical pins, while also incorporating horizontally arranged pins in a distinct pattern to facilitate the creation of regular or irregular polygons. These tools are specifically designed for plane geometry instruction; a 3D version has not yet been considered. The impact on students is evident as they eagerly build structures after printing. A magnification level of 1.25 is generally recommended for optimal use.
