The Out Of Marbles team designs and sells 3D-printed marble tracks. Users can choose from a variety of lifting mechanisms and different modules that guide the marbles. The modules available can be moved, adding new unique trails. They differ from the existing 3D print providers on the market in the broad scope of what they offer, and the fun, modular marble tracks can be customised by the user, in terms of colour and also size. The team is currently focusing on those who already own a 3D printer, while also offering pre-printed marble tracks for those who do not have one. 3D printer users can also choose from a variety of different 3D printing options.
