Cubic Trisection

Cubic Trisection is a three-piece assembly puzzle, suggested by George Miller to Oskar van Deventer based on a idea by Robert Reid.  George Miller protogyped the first version on his 3D printer in 2004.  At that time, 3D printing was prohibitively expensive.  This version was 3-D printed on Oskar's new Dutchy 3D printer.  Each of the three pieces takes 2 hours and 13 minutes to print and 9.45 meters of PLA plastic filament.  The material is translucent, which was chosen to highlight the inner 15% infill gyroid structure that makes the pieces rigid and robust, while light at the same time.

Most people have a difficult time putting it together. They usually try and force the pieces to "snap" together, whereas they easily glide together when twisted along the main diagonal. It is best presented to your guests in its solved state.  Let them take it apart and watch them struggle to get the three identical pieces back together again...

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.
