Marble Coaster

I am not an expert designer and I am sure this does have some flaws.

This is rollercoaster for marbles. The file with the world large is fullscale and the physics have not been tested to see if the marble will successfully go from point A to point B. The original design was for a competition held by Luban3D for creating a design using their new Spin tool and had to be scaled down. Once it was scaled down, no marble would fit for actual testing. This will need some supports when printing.

Update 14 Jun - Added the Spin.stl which is the Marble_Coaster_Final file ran through the Spin Feature within LuBan3D.
