3D model description

####Make Your Own Platonic Octahedron

Vertex connectors and edges that can be snapped together to make a Platonic Octahedron.

To make an octahedron, one need 6(V) vertex connectors and 12(E) edges. Once assembled, the structure has 8 (F) equilateral triangle faces : V + F – E = 2.

Among the Files

Vertex connector at two level of tolerance (regular and loose)
Edge bars of various lengths.

Please print one connector and one edge first to try out the tolerance. A resolution of 0.2mm 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 octahedral edges with those for the other Platonic solids, because they have different dihedral angles.

Have fun!
