Deck and discard Holder Modified

This is only a version of the original from Djomp http://www.thingiverse.com/thing:434793/#comments

After using the version of Djomp, i saw it was a llitle bit fragile, so i reinforced the structure and now its more strong.

New version folder, lighter, stronger and smaller. http://www.thingiverse.com/thing:759978
