About this 3D model

I got tired of my parking placard for work tangling from my mirror, so I designed this simple holder. All you need is some double-sided tape (3M makes some good stuff)... cut it to match the four recesses, then stick it to the inside of your windshield at the desired location. Voila! no more dangly-bits :) I don't have a printer yet, so please share your pics!
