Marble Coaster

thingiverse

I am not a professional designer, and I'm certain this project has some glaring flaws. This rollercoaster for marbles is an ambitious design that scales up to fullsize, but the physics behind it have yet to be thoroughly tested - will the marble successfully make its way from point A to point B? The original design was created as part of a Luban3D competition to showcase their new Spin tool. However, after scaling down the design, no marble could fit for actual testing. This model will require additional supports when printed. Update 14 Jun - I've added the Spin.stl file, which is the Marble_Coaster_Final design that was run through LuBan3D's Spin Feature. https://www.luban3d.com/
