Papercraft Box Generator
Pick a box style — closed rectangular box, open tray, lidded gift box (base plus a slightly larger lid as two nets) or a pillow box with curved ends — enter width, depth and height in millimeters or inches, and get the unfolded net as a template: solid cut lines, dashed fold lines (long dashes for mountain folds, short dashes for valley folds) and trapezoid glue tabs on the right edges. The preview labels every dimension, warns when the net will not fit your paper size, and can add a centimeter ruler along the edge so you can verify the print scale. Print it or export PNG/SVG.

Notes
- Print at 100% scale ("actual size") — never "fit to page" — and the template comes out at true physical dimensions; the optional printed ruler lets you check with a real one.
- The lid of the gift box is generated 1 mm larger than the base in width and depth (paper-thickness allowance) so it slides on without forcing.
- The SVG export uses real millimeter coordinates, so it can go straight into a cutting machine (Cricut, Silhouette) — cut the solid lines, score the dashed ones.
