This is the Google Docs blue paper-looking icon. It is 40mm long, which is a good keychain size - and it has a hole for the keychain. It is meant to be printed in blue. Scale it down to half size for making earrings or bracelet charms, and to double size for a really cool backpack charm.
I wrote about this on my 3D-printing journal at http://MkrClub.com (post at: http://www.mkrclub.com/2015/01/google-docs-icon-3d-modeled-and-printed.html)

Note - this model was created by one of the Google Docs/Drive co-founders :) - I mean, really, who else would waste their time modeling this thing ;) find me on twitter at http://twitter.com/jrochelle

Autodesk 123D used.
Drew outline shape with cut corner. Extruded that.
Created triangle extruded to same thickness separately. Tilted and combined onto cut corner of main shape.
Created rectangles to be cut outs for lines in the icon - combined/subtracted to create cut-outs.
Bam!
