Trefoil Knot + Three Pages

This is a variation of the **Trefoil Knot** that I made for my undergraduate research project [(see original here)](http://www.thingiverse.com/thing:243260). Consider a trefoil knot as the spine of a book. What does a single page look like inside [(previous model)](http://www.thingiverse.com/thing:331530)? Now what about three pages spaced equidistant from each other?

The .stl file was made using Mathematica's RegionPlot3D with a PlotPoints of 200.
