To print and assemble this succesfully you will have to cut some of the files like the body and the head in two parts.
To assemble this put the chicken heads on the bodies and glue the two body parts together. Make sure you don't glue the heads to the bodies. Than glue the chickens and the handle onto the board. After that you can place something heavy into the ball and glue the two parts together. Than you can run the cords thru the holes and connect them to the ball and the chickens. Finally glue part06 onto the chickens.
