Cross living-hinge box

A plus with even arms. First communion, confirmation and baptism gifts, rosary boxes.

Plus with even arms. The wall is one strip of plywood with a living hinge cut into it, so the whole outline wraps from a flat sheet. Set the size in millimetres, pick a hinge pattern and a lid, watch it fold in 3D, then export the cut file for your laser.

These numbers come from the same engine that makes your file, built at the size the Studio suggests with the Straight Lattice hinge. Change the size, stock or pattern and they update live.

The lid, as the laser sees it. Red is the cut, blue is the scored lid art.
Three lids

Drop-in, Snap-lock, Magnetic Lip. Every lid works with every shape.

Three stocks

3 mm, 4 mm, 6 mm. Hinge spacing and corner radii follow the thickness.

Kerf-compensated

Tabs grow and slots shrink by half your kerf, so parts press-fit without sanding.

Hinge patterns

Hinges that suit a cross

Any of the 21 patterns works on this shape; the cut spacing adapts to each curve of the wall. These four suit the Geometric collection. Each link opens the Cross with that hinge.

Before you cut

From file to finished box

Import the SVG at 1:1, give the blue layer a light score pass and the red layer a full cut, score first, then cut. The guides cover settings by machine and material, assembly, and selling what you make.

Questions about the cross box

Is the Cross box free to export?

You can design it, change every setting and fold it in 3D for free. Exporting its cut file needs Pro: $9 per month, $59 per year, $149 one-time. The Rounded Box, Curved Cylinder and Hexagon export free, so you can test your laser settings before you buy.

What size can a cross box be?

Anything from 60 to 400 mm across and 30 to 250 mm tall; the suggested size is 150 × 150 mm. Picking the shape keeps your current scale and applies its proportions, then you can set the width and length to the millimetre. Curves need a minimum radius for the hinge to bend (8 mm on 3 mm stock, 10 mm on 4 mm, 15 mm on 6 mm), and the studio warns you if a size is too small for your stock.

Which lasers and software can cut it?

Any laser whose software imports SVG or DXF at 1:1 in millimetres: LightBurn (Omtech, Monport, Ortur, Atomstack, Creality, K40 and most CO₂ and diode machines), xTool Creative Space, Glowforge (SVG), LaserGRBL and Inkscape. The file has a red cut layer, a blue score layer for the lid art and fold marks, and a black sheet boundary.

What material should I cut it from?

3, 4 or 6 mm flat sheet stock. Baltic birch plywood bends best; poplar plywood and MDF work for gentler curves. The hinge spacing is sized for the thickness you pick, and the free bend test strip tells you how far your particular sheet will go.

Can I sell cross boxes I make with it?

Yes. Boxes you cut from your exports are yours to sell, on Etsy, at fairs or anywhere else. What you may not do is resell or share the cut files themselves as a template.
