This design for the science design challenge is a cable holder for the ISS. It is a rectangular block with a hole in the middle that a cable can run through. The way it would be used is that it could be attached with Velcro to any surface in the module. Then a cable can run through it and the tool will hold the cable in place. I decided to design this tool because the ISS has hundreds of loose cables and I thought it would be a good idea to bring down the hazard levels of damaged cables.
