I took a lego cloak by Hexx (http://www.thingiverse.com/thing:290112/#files) put it in Tinkercad, Loaded the Giant Lego Batman body of mattk007 (http://www.thingiverse.com/thing:85270) and fit the cloak to the giant Lego figurine. I had to do some modification such as the semi-circle knockouts on the bottom of the cloak) and some minor repair around the neck. I also made sure the hole at the top will fit the batman body.
