Sphinxy was saved as an STL file and handed over to Zeven Rodriguez for rapid prototyping. As Zeven's mill is only 3 axis, quite a bit of mesh slicing was required to deal with the ins, outs and undercuts. As can be seen in the image below, all of the parts milled quite nicely in extruded polystyrene.
The parts and pieces were glued together and then textured by Eric Hagan, the leader of Kara's sugar crew to emulate the surface of the Domino original.
The finished prototype was then handed over to Tim Daly for molding and casting Sphinxy just like a real rubber ducky, squeaker and all
