On May 15th, 2008 I put out a ‘design request’ for the “Lorente's Florid Sphere” puzzle.
This is the puzzle that was initially shown in the Scientific American article by Douglas Hofstadter in July 1982.
For reference, see the following link:viewtopic.php?f=9&t=9777
It was proposed to design such a puzzle based on a Rainbow Cube.
Although I believe that this would still be possible, Adam (Puzzlemaster42) took a different route and designed such a puzzle based on a new mechanism.
The puzzle parts have been 3d-printed (sls), assembled and stickered.
The results are shown below.
I choose for an 8-colour stickering similar to the colouring of the Dino Star puzzles.

Actually, Adam made 2 design variations; one with oval kind of pieces requiring stickering and one with split (‘clickable’) pieces that can be painted individually (shown below in white).

The turning of the puzzle is quite smooth, although care has to be taken to align the parts well (not because of hooking but because alignment has to be precise before a next rotation can be made).

Thanks a lot to Adam for preparing the design.
