This puzzle took top honors as a Jury 1st Prize winner in the 2011 IPP Puzzle Design competition held in Berlin. "Two open-ended Superstrings with the correct spin can merge into a super-symmetrical cube." The idea for this puzzle came from designing shapes based on two interlocked tetrahedra. I drew inspiration from "string theory" and "super-symmetry," searching for shapes that were both symmetrical and remarkably similar. Although they may look identical, the two pieces have distinct differences. Print Settings Printer: Mendel90 Rafts: No Supports: Yes Resolution: 0.2 mm Infill: 30 Notes: My competition entry was printed in nylon by Shapeways and is still available to purchase on their site - https://www.shapeways.com/product/79EZ8M87R/superstrings. With good support material settings, you can also print this at home using an FDM printer. Post-Printing Taking the two pieces apart isn't too difficult; reassembling them back into a cube requires more effort. Hold one of the pieces steady and move the other piece through the correct sequence of lateral and rotational moves. The solution document is located in ThingFiles.
