Part 3 of the SPIES puzzle series designed by Alfons Eyckmans

Part 3 of the SPIES puzzle series from designer Alfons Eyckmans, who has kindly given permission to provide this model. Named SPIES #5, It is a great assembly puzzle with a unique solution.

You can build SPIES #5 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.

The goal is to assemble the parts into the shape shown in the pictures. 

This puzzle requires a minimum of 35 moves to put all the pieces in their correct position. 

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 (blue 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.

If you wish to print the main plate in 2 colours, to highlight the text, simply use a manual color change.  I've also included the 2-color 3mf plate file for my MK3S+. 

The video below introduces this puzzle and provides some hints.
