A construction kit

A construction kit comprising:

• a plurality of connector hubs, wherein each connector hub has a spherical or sphere-like shape with a substantially hollow central zone and includes
• a first pair of connecting formations defining a first axis of the connector hub between them,
• a second pair of connecting formations defining a second axis of the connector hub between them, the first axis and the second axis being orthogonal to each other and intersecting so as to define a vertex of the connector hub, and
• a third axis which is orthogonal to the first axis and the second axis and intersects both the first axis and the second axis at the vertex, at least one additional connecting formation being defined on the third axis;
• a plurality of links, wherein each link has a hub attachment formation configured to mate with each of the connecting formations of the connector hub for removable connection of the link to the connector hub, the hub attachment formation including a male connecting element and a flange, the male connecting element being configured to be connected to one of the connecting formations of the connector hub along the axis associated with that connecting formation, the axis being one of the first axis, the second axis and the third axis, and the flange defining a mating surface which is shaped and dimensioned to mate with a complemental surface of the connector hub when the male connecting element is connected to the connecting formation, each link further having a connector attachment formation located at or near a link face of the link, the link face being substantially perpendicular to a linking axis defined by the link, wherein the linking axis of each link intersects the vertex of the connector hub to which the link is connected, in use, wherein each link is configured such that a linking distance of the link, which is defined as the distance between the link face of the link and the vertex of the connector hub to which it is connected in use, is or remains substantially constant irrespective of an angular position of the link relative to the connector hub, and wherein the connector hubs and the links are shaped and dimensioned such that, when two of the links are to be connected to the same connector hub in use, the connector hub is capable of accommodating connection of the two links to adjacent connecting formations of the connector hub provided that there is an angular gap of at least 15 degrees between the linking axes of the two links;
• and
• a plurality of elongate connectors, wherein each connector has end formations at both ends thereof, each end formation being configured to mate with the connector attachment formation of the link for removable connection of the connector to the link, and via the link, to the connector hub.
