Using these files with a cutting machine
Every file is a single <path> with no fills, groups, or clipping — the
shape a cutting workflow wants. In Cricut Design Space or Silhouette Studio, import the SVG
and assign the path to a draw operation (with a pen adapter) or a cut
operation. For cutting, the open lattice designs need care: everything the blade separates
falls out, so treat dense designs as engrave/score patterns and reserve
actual cutting for the simple, bold shapes.
A rough guide by design density: the 3-, 4-, and 7-petal designs cut well from cardstock and adhesive vinyl; the 8-, 9-, and 15-petal designs work as vinyl if you're patient with weeding, and beautifully as laser engraving on wood or acrylic; the 32-petal and denser webs are engrave-only on most materials — or perfect pen-plotter drawings, which is closest to what a spirograph is anyway. On a laser, run dense files as vector engrave at low power; the crossing lines pass over some points twice, so high power will burn through at the intersections.
Scaling, editing, and license
SVGs scale losslessly — these are 800×800 units but print or cut identically at any size. In Illustrator, Affinity, Inkscape, or Figma you can restyle the stroke, add fills between crossings, or combine several files into a layered design (each file notes its gear recipe in a comment, and the same recipe opens in the visualizer if you'd rather remix it there — the math explainer covers what the numbers mean). All files are free for personal use — school projects, gifts, home décor, craft fairs included. Please don't resell the files themselves. If you use them somewhere fun, a link back to spirography.com is appreciated but never required.
