This fort building kit is presented as a modular construction set consisting of straight rods and multi-connection spherical connectors.
A rod-and-joint framework defines the building kit as a single contained unit.
Visible straight rods and perforated connector balls form the clearly identifiable features.

Manual insertion of rods into the connector openings allows the building kit to operate as described.
Structural assembly occurs through direct physical connection of the components.
Movement remains limited to assembly and disassembly of the frame structure during use.
These combined characteristics lead naturally to the details below.

• Fort Building Kit with modular rod and connector components

• A single fort building kit presented as one complete unit

• Plastic connector spheres surrounding internal insertion points

• Manual structural assembly during operation

• Rod insertion into multi-angle connector joints
