Three-Way, 3D, Joint Model

####Three-Way Joint Model

This is a three-way joint. It takes three copies of the same piece to make a 3-way joint. It is based on the geometric ideas behind a Tsugite dissection. I started with a 50 mm cube, removed a corner using the plane containing three vertices around another vertex, and then dissected the cube into thirds from the equilateral triangle. The result is three pairs that form a three-way joint. I added some extra face to connect each pair, which becomes one third of a three-way joint. Enough tolerance is left on the interior faces to allow free assembly. If desired, a few drops of glue can be used for a permanent joint. The joint is a functional structure; it is mathematically appealing!
