Hi Shapeways fans, Caged Soma was designed by Andreas Roever at my request. Andreas spent many hours configuring Burrtools, in order to find a Soma design that satisfies the requirements: six "hooked" pieces going into a cage. Andreas found that there exist only four designs that work. Of those four, there is only one higher-level design (1.1.1.1.3.2). Obviously, that is the design that I had to prototype. All pieces hook together, so they can come out only one at a time. I printed all pieces hollow, so one can have a look inside the cube and also have some looks all the way through. Watch the YouTube video. Download the CAD file to print-it-yourself. See solution at Imgur. Buy the puzzle at my Shapeways Shop. Read more at the Non-Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
