Sliding image puzzle

These are my 3d printed version of the classic sliding 15 puzzle.
I've added a storage box, cover with sample and spacer. The puzzle can be made separately, but also in the box, which makes sliding easier. The spacer is intended to fill the open space so that the pieces do not just shift.

I printed everything on the Prusa Mini+
The puzzle with a layer thickness of 0.15mm
The box and lid with a layer thickness 0.20mm
Slicer low thickness 0.25mm
Of course the puzzle and the lid with example can be printed in 1 color, but I made the prints in 2 colors.
The images contain the screenshots of the color change.
The color changes are also incorporated in the Gcodes
