Tetty-Jax

This is a derived work model. It has been processed by NetGen5.3 to create a tetrahedral FEM mesh (a tet mesh) inside and on the surface of the model. The tet mesh is exported in GMSH V2.X format. Using custom written code, all the edges of the tets are collected, sorted and duplicate edges are removed. The edges are Unioned together (as cylinders with spherical end caps) to produce a fully tetrahedral model. The model is then exported as an STL.

I would suggest printing this a tree supports BUT you might be successful printing without supports (due to the tetrahedral nature of the model). I was successful using support painting with tree support.
