Instructables user RaisedByRobots wanted to do something with old plastic soft drink bottles to help get organised. The solution? Cut the bottles in half, screw them into the wall and use them to organise cables.
This isn't the most aesthetically pleasing cable organiser we've seen, but it gets the job done and manages to provide a use for those soda bottles you might have laying around. RaisedbyRobots recommends using a hot knife or a soldering iron blade (and a fume mask, just in case) to cut the bottle in half. It's not glamourous, but it works.
