Made in meshmixer. I've included multiple versions, the second has the duck part scaled larger relative to the body, and the third has the beak at a steeper angle for easier printing. I think it's pretty neat how it resembles an ostrich with short legs and no wings.
Be sure to post a photo if you make one! I'd love to see how the model comes out on different printers.
Use a raft or brim if the model does not stick well to your print bed.
