The phototutorial below starts from a hexagon with an 8×8×8 grid. Folded this way, the model has several unnecessary creases visible on its front side.
In order to avoid creating them, start with a sheet precreased as in the picture below instead, and take care to avoid creating any new creases during the
initial collapse. Note that this PreCP is unusual in that it has 3-fold rotational symmetry but lacks axial symmetry: for example the crease line closest to
the vertical axis of symmetry (⅛ grid) is present right to the vertical axis of symmetry but is not a continuous line on its left side.
