The file 'Puzzle Rhombic Dodecahedron 3D Printer Model' is (stp,scad,stl,dxf) file type, size is 183.5KB.
This is the shape of a rhombic dodecahedron divided into four identical pieces in an unintuitive way. Luckily you don't need to be familiar with the final shape: when you discover how to fit the pieces together they will converge into a rhombic dodecahedron.
Here's a YouTube video showing how the puzzle fits together: http://www.youtube.com/watch?v=MpmkWj1LPwE
