SPIES #6 Final puzzle in the series of Alfons Eyckmans

SPIES #6  is the final instalment of this SERIES of puzzles designed by Alfons Eyckmans, who has kindly given permission to provide this model. It is the most difficult assembly puzzle of the lot. Please respect the copyright and only create the puzzle for your own enjoyment.

You can build SPIES #6 from the STL files below. I used PLA, 0.3 layer height, 3 perimeters for all parts. You can build at a 0.2 layer height for increased quality.

I feel this is too difficult to assemble with no prior knowledge as the plates and fork could have hundreds of possibilities, so I've presented it so that you can assemble it without knowing the solution and then work to take it apart.

To assemble, you'll use a 2-piece inscribed plate. The video below will show you how to use the 2-part plate to create the puzzle. You'll need two M3 screws (12mm +/- 4mm)

This puzzle requires a minimum of 32 moves to remove the first part. 

NO ROTATIONS are allowed if you wish to discover the intended solution. That is, all parts will shift up/down, left/right or backwards/forwards. If you attempt to manipulate the puzzle while holding in an upright position, you may find that the pieces (red in the picture) may rotate due to gravity. There may be non-intended solutions if you rotate parts. I often work on these puzzles on a table top to prevent unwanted rotations.
