"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"
The set of pieces took 26¾ hours to 3D print on a Dutchy 3D printer. 71 meter of 1.75-mm PLA filament was used to print it. The puzzle weights 220 gram.
Oskar van Deventer, has created many different puzzles including his brand of Oskar Puzzles which are mechanical puzzles and objects that can only exist thanks to 3D printing technology. Since 1978, he has been creating hundreds of mechanical puzzles, making him one of the world's most prolific designers. Several of his innovative designs are commercially available.
