The set includes additional connectors in the form of “empty” boxes, which can be arranged in any way according to the diagram.

The system is simple: each box has a specific height, and when arranged together, they form a level at a specific height in a 4/3/2 configuration, in the order small, medium, large.

The set also includes a double base and two leveling spacers, one double and one single.

The set does not include platforms with boxes. All 3 levels can be found here: https://thangs.com/designer/WIKK/3d-model/OrbitStack%20-%20M2%2C%20M3%2C%20M4-1466637
