This model can be used to impress an Escher design into a lonely deserted beach to confuse passers by...
A smaller version will also make a fine cookie cutter...
The Customizer interface allows you to set wall thickness and overall size, as well as the internal detail offset for cookies.
Also see it tiled for your amusement... but only print one :)
Originally for the Summer Steam Math Challenge (but finished it too late).
Print it coarse if large for the Beach. Finer if for making cookies.
Choose the wall thickness so its slices well for your machine.
PLA works well..
Made from my inkscape drawing where I was able to test the tiling of the pattern.
Then exported using Dan Newman's inkscape openSCAD exporter.
Based on the Woodblock version of Escher's design.
