SummaryThe Cord Cobra is a heavy duty extension cord tie that stays with your cord whether the cord is in use or hanging up. It simply uses (1) one foot piece of 550 Cord and (2) 3D printed pieces. When your cord is being used, simply wrap the Cord Cobra around the end and clip it on. I'm currently working on a version for the traditional flat power cord for items around your house. Need 550 Cord? These dudes have a cool selection. http://tinyurl.com/mzjxn9v InstructionsPrints without support.
