Tetrahedra and Icosahedra

This is Blas’s icosahedra and tetrahedra set that was made as a math project. Then he made it for a present. Later on the Makerspace Business Club started selling them. A tetrahedron has four sides each side has a triangle face. With that in mind Blas decided to add puzzle edges to the sides of the triangles. Inside the big tetrahedra there are a bunch of triangle sides that are used for having fun and creating cool things. It is possible to make an icosahedra with the little triangles. Each edge of the small triangles have either one or two tabs for attaching one to another. Which means there are four different types of puzzle piece. They are fun to play with.
