Tetrahedron 2

Update 2/26/2015 Thanks to DesignMakeTeach for suggestions for improving this model. I've redone the model with these in mind. New file is tetrahedron_keller_2016.stl.

This model is the tetrahedron defined by equations y=−6, z=0, z=x+4, and 2x+y+z=4. The equations are printed on the model.

This model was designed and printed by my WLU summer research student Ryan McDonnell ('17). See http://mathvis.academic.wlu.edu/2015/07/14/tetrahedra/ for more information.
