Your Own Platonic Tetrahedron
Vertex connectors and edges that can be snapped together to make a Platonic Tetrahedron. As a design project, the tetrahedron is slightly different than other Platonic solids. To make the edges, I extruded the base triangle toward the center of the tetrahedron.
To make a tetrahedron, one need 4(V) vertex connectors and 6(E) edges. Once assembled, the structure has 4 (F) equilateral triangle faces : V + F – E = 2.
Edge bars of various lengths.
Please print one connector and one edge first to try out the tolerance. A resolution of 0.2 mm works well for me. You can play with the resolution to adjust the tightness between the vertex connector and the edge.
The angles between the V-connector and edges are getting small. Toward the end of the project, please bend the structure a little bit, if necessary, to align the edges with the slots. A pair pliers might be handy, too.
Also, please do not mix tetrahedral edges with those for the other Platonic solids, because they have different angles.
STEAM educator, learning from and working with K-12 STEAM teachers to explore new ideas of teaching and engagement. I firmly believe ART is at the core of STEM learning or all human learning! I owe my ideas and designs to the hundreds of K-12 children and teachers and university professors I have had the pleasure of working with, in multiple disciplines-- math, science,engineering language arts, social studies, early childhood education and more! All mistakes, of course, are mine! There is no warranty or liability whatsoever implied or explicit behind the designs or ideas. They are all posted for their potential educational values.
When working with children, please strictly observe all safety and health procedures! Please refer to the NSTA safety guides: http://www.nsta.org/safety/.
