Cubic Cable Holder was created in 2013 when I was a design student at RISD,
Here listed a few original posts from around that time:

Unfortunately the work has been plagiarized on Kickstarter and Amazon for several times. As I am taking legal action against the plagiarists, please support original design and help me make CCH a reality. :)
Generally the smooth surface of metal is unable to firmly grip onto glass, coated wood, or another metal surfaces. CCH features a thin layer of rubber pad on the bottom that can provide a sturdy grip and protect the table surface from being scratched.
Though of ample weight, the cubes will easily slide around without the rubber pad, thus fail to anchor any cables.
