This is a 3D print add-on and not an original from Ravensburger!

The cardboard base plates can also be used as levels for GraviTrax. The Plate-Connector provides good support for this, as it is inserted through the base plate and thus provides a connection to the height bricks under the base plate. The biggest advantage of the plate connectors is that you can continue building directly on top.
