Two color Escher lizard

I printed the original download files and the pieces wouldn't fit together. So I used the dxf and created a new part in Fusion 360 that is 0.25 mm smaller all around. I also added two levels of extrusion so that the parts could be (if desired) printed in two colors. The photo shows the results of this.

The dxf made a large lizard so I print the pieces at 50%. I left it large in case someone wants to print big lizards.
