Print Flat - Roll Into 3D, Heptagonal Column

Had an idea for a way to print something flat, but then fold it up into the intended 3D shape. Should work well with anything conical/column-like, including, say, wings!

EDIT: I made a wing using this technique, which I've take to calling Flat-Roll... Here it is: http://www.thingiverse.com/thing:483 (I kinda forgot to make it a derivative of this one, not used to that feature working again)

This rests on the notion (or hope?) that if you print something sufficiently thin, it will bend with
