Need some help on a project

I have a project that I am working on and there is something that I need that I can’t find anywhere (a file or help on making a part).

What I need is to be able to make or acquire the file for a retractable USB cable. I am mainly looking for some help on how to make one, but I would be just as happy for the file itself so I can understand what I would need to do to make my own. A tutorial or instructions on how to make it, alongside the cad file would be the best of both worlds.

I am using Autodesk Inventor 2014, but I posted it here in this section because I don’t need it to be Autodesk exclusive and I want more people to be able to see this post.

I think there are a few things can can help you out.

  1. Search http://www.3dcontentcentral.com
  2. Buy a retractable USB cable and take it apart
  3. Look for inspiration in a tape measure or other retracting mechanism (http://answers.yahoo.com/question/index?qid=20090815105809AANfIFg)
