This is a bird leg that can be attached to various fake birds made of styrofoam and feathers (or domething else if you like), like Easter chickens or some similar stuff. Mirror it in your slicer to get the second one and print it on a raft. The bird should stand properly if it's not too big or top-heavy and the legs are inserted properly. The leg has a shaft for easy installation in styrofoam that doesn't require glue.
