Made with Inkscape+Gimp, I used to store my discs inside it. A paper with some thickness is required. It is required to glue the sides of the packaging, to cut the semi-circle at the top with a stilleto and everything else with scissor.

The Tux image isn't mine(just adjusted the color and opacity), he and the ubuntu logos are their authors property. Please do not remove the credits at the packaging backside, do what you wish besides what was requested.

Click on the image to download, the target adress appears at the bottom-left on firefox.

Obs: The package is almost 100% enviroment friendly, as it is made of paper(thick paper), it lasts long and ocuppy less space than the regular cd cover.
