My daughter started a new job at a company that uses keycards for access. She came home with this plain white keycard in a clear envelope holder on a retractable tether. Totally generic. Not okay - not my kid, this we need to fix. So I suggested a cool holder that I would custom design for her but it should be something that she thought looked cool. Digging into her childhood she came up with the Thundercats. See? I raise them right - nerds to the end. So I modeled this badge holder to fit a standard ID card badge and remixed Tmatos cool Thundercats logo (http://www.thingiverse.com/thing:26996) to fit.
