This 16 spoke wagon wheel was typical of wheels to support heavy wagons, in particular those bagage wagons on a railroad circus. They can replace the rubber wheels on my Circus Commissary Wagon posted earlier.The wheel is designed with one flat side for raftess, suport free printing. Circus model builders are often chalenged to find wheels scaled to fit the prototype wagon. With 3D printing one can always scale an .stl model for a perfect fit.
