Belt (clothing) for Flexible PLA or Nylon

I modelled this belt based on one that I use. I intend to print it using Nylon but haven't done so yet, however I figured it would be useful to those people that are buying the new flexible PLA filament from Makerbot.
The cinto.scad OpenSCAD file uses the small library 2dgraph.scad that I added for completeness. I am not author of the library, I got it from this address: http://curriculum.makerbot.com/daily_tutorial/openscad/openscad_05.html
I don't have a buckle for it yet. I intend to model such a thing in the next versions of the belt.
