This wonderful custom built puzzle was created from scratch.
No single part of any known puzzle mechanism is used. As a puzzle it is simple. Only 180 degree turns available and only six parts, so there are only 48 permutations.
David also made version with straight and wavy cuts, shown in images 6 and 7.
And he made a half transparent version shown in image 10.
In 2016 a mass produced version of the curved puzzle hit the market under the name "Qboid - The 1.2.3 pocket puzzle", shown in images 8 and 9.
