A three-dimensional world map cut at 30 degrees latitude and longitude.
It looks like a puzzle and could be used for educational purposes.
The original size is 200mm x 120mm; you can change the size and put it on your favorite frame.
Changing the color by 10mm in LAYER height will be just right.
If you like the design, I would be flattered to receive a little tip via PayPal:
