This is a large drinking bird--made from a 3d scanned normal bird.
Start by painting the glass white on a normal drinking bird. Turn him on his head and scan. The hat is too thin to scan well, so I'll design a hat.
Print the body and head, enlarged about 350%.
Print the hat and axle. Files are available at http://www.thingiverse.com/thing:177456
Secure the bird's body using a screw (back side). Slide the axle over the tube, then secure the head with a screw.
Take a 1" x 2" by four feet long piece of oak and drill a 1 1/8" diameter hole in the center. Cut the board in half through the center of the hole.
Paint the "legs" your favorite color.
Design a foot in clay and scan it.
Merge the scanned foot with a designed base (I merge the STL files in TinkerCad).
Slide the legs into the base.
Glue googly eyes onto the head. Attach the hat by melting it to the head with a soldering iron (use good ventilation or outside).
Set the bird assembly onto the legs.
Give the bird a push every time you walk by--it will bob for about a minute.
