The Free Universal Construction Kit
Summary
The Free Universal Construction Kit is a project to create adapters that enable interoperability among ten popular construction toy systems using 3D-printed parts. It discusses motivation for cross-brand compatibility, distribution via STL files and posters, licensing under CC BY-NC-SA 3.0 Unported, and legal considerations around intellectual property. The article positions interoperability as a civic act and critiques mass-market lock-in.
