Details

Corner Connectors are the joint of the whole system. Each one bridges the corners of neighbouring cubes and pulls them into alignment, so a stack behaves like one piece of furniture instead of a pile of boxes. They also form the rounded outer corner you see on a finished grid.

Three geometries cover every position in a build. Singles finish an outside corner, doubles join two cubes along an edge, and four-corner connectors sit at the interior junctions where four cubes meet. A grid needs a mix, and the ratio depends on its shape.

Tell us the grid you are building and we will work out the mix for you — it is easy to get wrong by eye, and ending up short of four-corner pieces is the usual mistake.
