Tetrahedron 1
thingiverse
Update 2/26/2016: DesignMakeTeach gets credit for spotting the mix-up in my original file, and I've got it fixed now - tetrahedron_1_2016.stl's the correct version. This model brings to life the tetrahedron defined by equations x+2y+z=2, x=2y, z=0, and x=0 - and they're all printed right on the model for good measure. Ryan McDonnell ('17), my talented WLU summer research student, designed and printed this model. Want to learn more about tetrahedra? Check out http://mathvis.academic.wlu.edu/2015/07/14/tetrahedra/.
