small notebook (moleskine) stencil with ridged ends

thingiverse

I took a popular shapes template (https://www.thingiverse.com/thing:3581304) and gave it a creative twist by adding two sizes of ridges along the short ends. I needed a straight edge in my compact moleskine notebook and wanted something that adds a bit more stiffness to its pages. I added several useful shapes, including double small triangles that serve as arrow heads pointing in two opposite directions. Since I use a dotted notebook with 4 dots per inch, the small shapes were designed to be precisely 6mm in size. The medium shapes measure 12.5mm and the large shapes come in at 24.5mm. To create a seamless fit, I carefully tailored the radius on both "inside" and "outside" corners of each shape.
