Fantastic 3D printed rolling ball "roller coasters"

Erik Pettersson from Enkoping, Sweden made an inspiring gear painting on his eMaker Huxley 3D printer back in 2011. Last year he created a beautiful 3D-printed Kinetic sculptures. This year Erik Pettersson comes up with another 3D printed art-project: the ball sculpture. It reminds me the SpaceWarp, line of popular build-it-yourself toy rolling ball "roller coasters" that originated in 1980 and manufactured by Japanese toy company Bandai. It allows users to construct their own futuristic roller coaster to the sizes and dimensions of their choice. Thick plastic tubing is cut in varying lengths to form the curves and loops of the track and is held in place by plastic rail track holders. Steel balls that follow along the track are carried back to the top of the coaster by a battery-powered screw conveyor.Inpired by Mark Bischof's beautiful rolling ball sculptures, Pettersson created his own art for home or office. The basic rule of this rolling ball sculpture is to allow glass or steel balls roll all the way on the track, as slowly as possible. This is a "lots of work" project. Pettersson started his design of the sculpture in August 2012. The designing part took about 100 hours in Google SketchUp. For keeping the sculpture a clean looking Pettersson kept only two types of curves on the track.
