Small toy, key ring or rattle with loose ball inside impossible to remove. This simple design was specially conceptualized to experiment with MakerBot, since it was not clear how act to stop the ball centered and suspended as was outlined in the Cad file. The machine created a thin thread that supported structural and position to the area, could be easily removed with a cutter.Made with MakerBot by a single extrusion. Designed in Rhinoceros, drawing an area in the center of a hexahedron with open faces. ABS plastic extrusion made ​​structure around the sphere to suspended in space. This structure will be easily removed with a cutter so that the ball is moving.
