Ive remixed a customised cable tie on the Thingiverse to add a label.
I bought some of these recently and thought they were a great idea.
This way you can have the cable tie and label any size you want and reusable.
I built on the original http://www.thingiverse.com/thing:58776
and added the extra dialogues and code to allow a label tab to be added to the original design. Its a paramaterised openscad design that has the parameters in comments at the head of the file that the Thingiverse customizer can read and offer in a dialogue.
