Escher Puzzle Circle Limit IV (Heaven and Hell)

https://www.mcescher.com/gallery/recognition-success/circle-limit-iv/

Puzzle made from Escher's Circle Limit IV (Heaven and Hell). Shape outlines traced in Illustrator with a .5mm line to adjust for printing tolerance. Once all the lines were prepped, the lines were "expanded," and the image was saved as an SVG. That file was imported into Fusion 360 where the shapes were extruded and saved as an STL.
