Here is the ellipsoid x^2/4 ^ y^2/6 +z^2/3=1, labeled with its equation. There is a second .stl file showing the surface without the equation. This model was designed and printed by my WLU summer research student Emily Jaekle ('16). For more information see http://mathvis.academic.wlu.edu/2015/07/16/quadratic-surfaces-ellipsoid/. This object was made on a MakerBot2X. We used the following settings: 2 shells 0.20mm layer height 10% infill (hexagonal pattern) Color matched supports Raft on We recommend building with a raft, just in case the object falls over. We also rotated this object before printing, so that the equations printed on the top, not the side.
