This design is comprised of eight recycling symbols arranged on the faces of a stellated octahedron. I came up with the concept a long time ago when I had to create a piece of "eco art" for a fundraiser. At the time I used SketchUp to design a version that I then made out of cardboard (recycled organic cereal boxes, to be exact). With Earth Day coming, I decided to pull up the old file and redo it for 3d printing. It came out even better than I had hoped! There are currently two sizes. The smaller was meant to be a pendant, but it ended up being too big. I currently have an even smaller version on order...it just shipped yesterday...but it's looking like it may not arrive in time for Earth Day. :-( Anyway, the sculptures are awesome. You can find them here: Recycling Sculpture (27mm) Recycling Sculpture (41mm) Thank you for you consideration! ~Sarah
