This is a (3,2) torus knot with the label T(3,2) added to the knot. One file has the knot with the label, the other with no label.
This model was designed and printed by my WLU summer research student Ryan McDonnell('17). See http://mathvis.academic.wlu.edu/2015/07/27/torus-knots/.
This object was printed on a FormLabs Form 1+ printer using the grey resin. We used 0.1mm slices and the print took 23.5mL. (The .form file used to print the object is included. )
The print came out really well :-)
