3D printable Deuterium model

3D printable Deuterium model based on a unified theory of physics as described in Tetryonics.


Pieces in STL:
Tetryons (tetrahedrons):
* neg_tet.stl - Negative tetryon, all four sides have negative polarity, modeled as holes
* pos_tet.stl - Positive tetryon, all four sides have positive polarity, modeled as connector tabs
* neut_tet.stl - Neutral tetryon, two sides are positive, two sides are negative. Modeled as 2 holes and 2 tabs.
* lepton_axl.stl - Magnetic/momentum axis that keeps
