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 leptons stable, modeled as a hollow tube with cutouts to slide negative tetryons into (although in practice any three tetryons can form leptons).
* electron_connector_left.stl - Left support arm for holding the electron in between the neutron and lepton magnetic axel. Connects a hole to the end of the lepton axel.
* electron_connector_right.stl - Right support arm, mirror image of the left.
