Sliding Tile Puzzle with Picture

This is based on https://www.thingiverse.com/thing:2828953 which creates a puzzle with numbered tiles.

I have altered it to use a picture (mono colour). The picture in mine is Alfa's four leaf clover the Quadrifoglio Verde (I used this image: https://www.thingiverse.com/thing:1637921).

Openscad file provided for further customisation.

If someone can point out a better way to slice up the picture, I'd love to hear it. This one is pretty clunky and slow to render.
