These trains use a unique print-in-place ball and socket joint to allow movement in all directions. The inner spheres print on top of tiny supports within the cavity of the neighbouring car. Once printed, a light twist of each car frees the ball within the cavity and the train can turn and bend. Be sure to let your print fully cool first! If the plastic is still soft, the connector may break when you try to move it.
This model contains small parts and is not suitable for young children.
Files come with or without custom supports. If you have trouble printing the files that come with custom supports, try using the files without supports and setting up your own supports in your slicer.
