Fifty-seven papers sit behind one sidebar: a Wulff net for crystallographers, Séyès ruling from French schools, genkō yōshi that reads right to left, a probit grid where normal data plots as a straight line, a goban in three sizes, cross-stitch grids counted to the Aida fabric. Set the spacing in millimetres or inches, pick A4 or Letter, and download a PDF, PNG or SVG with no signup. It even reminds you to print at 100%, or the grid won’t measure true.
