An open-book gesture. A folded literary detail.
Book envelope box SVG.
A little story to give.
Chapter Fold is an original book envelope box SVG for flexible, laser-approved uncoated cardstock. One connected shallow envelope-box net with a back panel, front panel, side walls, bottom gusset, top depth cap and triangular flap. The SVG page is 140 × 200 mm and the net/artwork bounds are 120 × 184 mm. The download includes the vector source, an English assembly and laser-preparation guide and an annotated fold map. Black decoration is surface engraving; blue folds require tested shallow scoring or hand-creasing.
Two pages in graphic form.
A literary envelope motif.
Chapter Fold places two curved book-page silhouettes beneath the flap of a shallow cardstock envelope box. The undecorated gap between the pages remains unengraved, and a ribbon secures the flap through two aligned holes. The book theme describes the decoration; check the nominal panel dimensions and a physical prototype before choosing small contents.
An open book formed by two separate curved page silhouettes engraved below the triangular front flap. The center gap is unengraved cardstock; no lettering or page-line cuts. No enclosed decorative cut-through windows are supplied. The red cutting paths define one outside net boundary and two aligned 3 mm ribbon holes. Supply a ribbon with a bulky stopper knot inside the front hole; both tails pass through the front and aligned flap holes and form a snug outer bow. Check that the knot cannot pass through the 3 mm hole. The closure is not self-locking or load-rated.
The images illustrate a possible finished appearance and setting. Digital SVG, English guide and annotated fold map only; finished boxes, cardstock, ribbon, adhesive, contents, tools and styling props are not included.

| Download | ZIP containing exactly three files: chapter-fold-book-envelope-gift-box.svg, README.txt and fold-map.png; machine from the SVG and use the annotated PNG as a reference |
|---|---|
| SVG page and net bounds | 140 × 200 mm page; 120 × 184 mm net/artwork bounds before stroke width; allow machine-required sheet-edge and fixture clearance |
| Nominal envelope panels | 80 × 65 × 12 mm (width × height × depth) before stock, crease, kerf and adhesive allowances; not guaranteed internal capacity. The triangular flap has an 80 mm base and 30 mm height above the 12 mm top depth cap. |
| Layout | One connected shallow envelope-box net with a back panel, front panel, side walls, bottom gusset, top depth cap and triangular flap |
| Construction | 12 mm side walls and bottom gusset, 8 mm side glue tabs and a ribbon-retained triangular flap. The front artwork is vertically reversed on the flat SVG net so it becomes upright when assembled; preserve its registration. |
| Surface decoration | An open book formed by two separate curved page silhouettes engraved below the triangular front flap. The center gap is unengraved cardstock; no lettering or page-line cuts (2 black filled shapes) |
| Cut and fold operations | 3 red (#FF0000) closed unfilled CUT contours; 8 blue (#0000FF) open SCORE paths, both with centered 0.025 mm strokes; 2 black (#000000) closed filled ENGRAVE shapes without strokes. Test blue as shallow surface scoring or disable the entire blue group and hand-crease using the fold map. Never through-cut blue folds. Black decoration is light surface engraving, not cutting; disable engraving if it cannot be performed safely on the approved stock. |
| Fold breakdown | 4 side-wall/glue-tab folds, 2 bottom-gusset folds and 2 top-cap/flap folds |
| Closure | Supply a ribbon with a bulky stopper knot inside the front hole; both tails pass through the front and aligned flap holes and form a snug outer bow. Check that the knot cannot pass through the 3 mm hole. The closure is not self-locking or load-rated. |
| Material | Flexible, uncoated cardstock positively identified and approved for the exact machine, laser wavelength and chosen cutting, scoring and engraving processes; no universal thickness is specified. This is a folded-cardstock design, not a rigid wood, plywood or acrylic box. |

-
Verify the import
Extract the ZIP and import the SVG at 100%. Verify the 140 × 200 mm page and 120 × 184 mm net. Confirm that the exact cardstock is approved, the full design fits the usable bed and all three operation groups remain registered.
-
Test each operation
Assign red to cutting; test blue as a separate shallow score or disable all blue paths and hand-crease. Assign black fills to optional tested light engraving. Inspect Preview. Where supported, complete decoration and safe scoring before closure apertures and outside boundaries; check actual job order.
-
Assemble a complete prototype
Identify the four side-wall/glue-tab folds, two bottom-gusset folds and two top-cap/flap folds. The open-book motif is reversed vertically on the flat front panel so it becomes upright after folding; do not rotate the decoration independently. Raise the 12 mm side walls and turn the 8 mm glue tabs inward. Bring the front panel across the 12 mm bottom gusset. Bond each tab’s outward face to the inside of the corresponding front-edge strip, keep the envelope square and let the adhesive cure. Follow the complete shape-specific sequence in the assembly FAQ and supplied English guide. Supply a ribbon with a bulky stopper knot inside the front hole; both tails pass through the front and aligned flap holes and form a snug outer bow. Check that the knot cannot pass through the 3 mm hole. The closure is not self-locking or load-rated.
This design has not been physically test-cut, test-scored, test-engraved, assembled, adhesive-tested, fit-tested, closure-tested or load-tested. Test scrap, then make a complete prototype with your actual software, machine, approved cardstock, crease method and adhesive before producing a batch. No universal laser preset is supplied.
A literary gift envelope.
Useful preparation answers.
What files will I receive?
The ZIP contains chapter-fold-book-envelope-gift-box.svg, README.txt and fold-map.png. The source has 3 red cut contours, 8 blue fold paths and 2 black filled surface-engraving shapes in named groups. The English guide covers import, operation mapping, material checks, assembly, closure and usage terms. The annotated fold map is a reference image, rather than a machining file. Alternate formats, machine presets and physical goods are not included.
Is this a finished box, and what size can I make?
This is a digital folded-cardstock template, rather than a physical box. 80 × 65 × 12 mm (width × height × depth) before stock, crease, kerf and adhesive allowances; not guaranteed internal capacity. The triangular flap has an 80 mm base and 30 mm height above the 12 mm top depth cap. The images illustrate a possible finished appearance and setting. Digital SVG, English guide and annotated fold map only; finished boxes, cardstock, ribbon, adhesive, contents, tools and styling props are not included. The decoration describes a theme, not the size of an item that will fit. No finished-capacity, protective-packaging, shipping, food-contact or load-rating claim is supplied.
Which lines are cut, folded or engraved?
Red contains one outside net boundary and two aligned 3 mm ribbon holes. Blue contains 4 side-wall/glue-tab folds, 2 bottom-gusset folds and 2 top-cap/flap folds. Keep both line groups as centered 0.025 mm strokes. Test blue only as a shallow surface score, or disable the entire blue group and hand-crease using the map; never through-cut the folds. Black contains 2 filled shapes for optional light surface engraving, not holes or outline cuts. If engraving is unsuitable for the approved cardstock, disable it. Never use a display image as the cutting file.
How do I prepare it for Glowforge, xTool, Epilog or another laser?
Glowforge: Upload the SVG in the app supported by your exact model. Verify the page and net dimensions and map red to Cut. Inspect Simplify Strokes and the preview for thin blue fold paths. Use only a separately tested shallow Score setting, or set the entire blue group to Ignore and hand-crease from the map. Black fills are optional, tested light Engrave decoration. Colour alone does not establish settings.
xTool Studio / XCS: Use software supported by your model. Studio SVG import DPI and XCS import resizing can affect scale. Verify all dimensions. Map red to Cut, blue to a separately tested shallow Score or disable blue and hand-crease, and black fills to optional light Engrave. Score follows paths and can cut through with excessive settings; never use the cutting settings for folds.
Epilog: Open the SVG in supported vector graphics software and use the current driver or Dashboard for your exact model. The documented Illustrator-to-Dashboard route needs centered vector strokes no wider than 0.025 mm. Retain the supplied 0.025 mm red and blue strokes and verify vector recognition. Separate red cutting from a tested shallow blue vector mark through supported colour mapping or separate jobs; otherwise disable blue and hand-crease. Black fills are optional raster engraving. This is a conditional software route, rather than a universal direct machine import.
Other CO₂ or diode equipment: Confirm controller, software and wavelength support for the actual stock. On supported LightBurn systems, import the SVG, verify scale and map red to a tested Line cut layer, blue to a separate tested shallow Line mark or disable it for hand-creasing, and black filled shapes to an optional tested Fill engraving layer. Inspect Preview and process decoration and any safe score before releasing the outer boundaries. The laser source alone does not establish compatibility.
Which cardstock and laser settings should I use?
Flexible, uncoated cardstock positively identified and approved for the exact machine, laser wavelength and chosen cutting, scoring and engraving processes; no universal thickness is specified. This is a folded-cardstock design, not a rigid wood, plywood or acrylic box. Check all dyes, coatings and additives. A display colour does not prove laser suitability. Use only stock approved by the manufacturer and exact equipment instructions; avoid unknown, metallic, glittered, laminated, coated, PVC/vinyl or prohibited materials. Follow the maker’s exhaust, supervision, hold-down and fire procedures. Add glue, ribbon and contents after laser processing.
Custom stock needs its own settings checks. No universal power, speed, thickness or pass count is supplied. Excess scoring or engraving can cut through or weaken card. This design has not been physically test-cut, test-scored, test-engraved, assembled, adhesive-tested, fit-tested, closure-tested or load-tested. Test scrap, then make a complete prototype with your actual software, machine, approved cardstock, crease method and adhesive before producing a batch. No universal laser preset is supplied.
How do I assemble, close or resize the box?
- Pre-crease the eight folds. Identify the four side-wall/glue-tab folds, two bottom-gusset folds and two top-cap/flap folds. The open-book motif is reversed vertically on the flat front panel so it becomes upright after folding; do not rotate the decoration independently.
- Raise the sides and glue the front. Raise the 12 mm side walls and turn the 8 mm glue tabs inward. Bring the front panel across the 12 mm bottom gusset. Bond each tab’s outward face to the inside of the corresponding front-edge strip, keep the envelope square and let the adhesive cure.
- Install the ribbon stopper. Before closing, place a bulky stopper knot inside the front ribbon hole. Bring both ribbon tails through the front 3 mm hole to the outside. Choose and test a knot that cannot pass through the finished hole; ribbon is not included.
- Fold the cap and tie the flap. Fold the 12 mm top cap and bring the triangular flap down. Pass both ribbon tails through the aligned flap hole and tie a snug outside bow. Check alignment, knot retention and actual stock strength. This is not a self-locking or load-rated closure.
Supply a ribbon with a bulky stopper knot inside the front hole; both tails pass through the front and aligned flap holes and form a snug outer bow. Check that the knot cannot pass through the 3 mm hole. The closure is not self-locking or load-rated. Scale every structural part and operation together. Scaling changes tab widths, apertures, score spacing and overlaps without compensating for stock thickness, crease radius, kerf or adhesive. Make a new complete prototype after any change. Keep decoration registered with its panel. Choose only light intended contents after checking the actual closure.
