Parametric Gator Clip / Key Fob

This is a parametric key fob that can double as a clip of some sort.
Inspiration for this design was derived from hoeken's Gator Clip http://www.thingiverse.com/thing:507 and the Florida Gator's team logo.
I have uploaded three variations of the design in stl format, along with the dxf and scad files.

Note: Ensure the dxf and scad files are placed in the same folder in order to render properly in Openscad.
