This is a marble run model. Each part of the whole set is an individual piece, placed in postion to make a full sized set accurate to reference from the real life equivalent. The model in some of the images are textured with Corona, which should be part of the material file within the collection, but you can add your own textures if needed.

The full set has individual pieces, meaning when you use it, you can rearrange the parts to suit your vision of how the marble run will be used in your own 3D project. It is also possible to replicate the pieces as well so you can add more parts to the marble run and have a potential large and complicated set. The use of this model is up to you as you see fit. It also comes with a marble model with objects inside to replicate the look of a marble. It can also be changed if needed.
