This giant auxetic structure is an 8x8 variation with a total of 64 squares, each 30x30mm. Very satisfying when laying on a flat surface. Sure to be a long print, so make sure your printer manages these well by printing a smaller variation first!
Printing Guidelines
Fairly loose requirements, just make sure your printer isn't overextruding and has decent cooling so none of the parts fuse. I used 0.16mm layer height, 3 shells. No supports!
