Hex Hole End of the Roll Phone Stand

This is another remixed version of my previous 2 angle phone stand design, instead of making it thinner I did some hex cutouts aligned so that supports weren't needed.  In this case the stiffness didn't really change much from the original version.   It works with both large and small phones.  The structure was shelled to minimize material (main body is a single extrusion width), but the ribs on the edges stiffen the structure significantly.  Prusa slicer says 1.91m of filament for the print.  It should be printed on edge as shown in the .stl, the transitions have been chamfered so that no supports are needed (and for a bit more strength).
