The file 'Construction System 197 3D Printer Model' is (stl) file type, size is 10.4KB.
This is one of my all-time favorite construction systems. It's comprised of a single primitive. When six are joined into a cube, you have a building block that can connect on any face to any other cube. It's simple to print and amenable to injection molding. Enjoy!
Also check out Construction System 200 for a single-cube based version of this. Harder to print, but stronger and more stable.
