Free Universal Construction Kit offers open-source adapters to connect popular construction toy systems

The article points to The Free Universal Construction Kit, a project offering adapters that let different construction toy systems work together. The concept centers on interoperability, using freely available designs to bridge otherwise incompatible products.

The project reflects a broader maker-culture push toward open designs that reduce lock-in across consumer ecosystems. It also foreshadows how 3D printing can challenge proprietary accessory markets by letting users create compatibility layers themselves.
