This is a Lego-compatible, two headed, three-legged mini-figure. Legs are fully moveable. Only the torso and the hips/legs are included, you must provide your own heads and arms.
It’s available on Shapeways, and there are full-size photos on Flickr.
The torso was printed slightly warped, and it cracked when I put the arms in. If your print is warped or distorted, ask Shapeways for a reprint. All the edges should be straight and the flat surfaces should be completely flat.
