Curved Cylinder living-hinge box

A round or oval box where the whole wall is one even wrap. Candle gifts, pen pots, a round keepsake box.

Round or oval, even wrap. 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.

Curved Cylinder lid as the laser sees it: red cut outline and blue scored lid art
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 curved cylinder

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

Straight Lattice: Staggered straight slots in a brick bond, the pattern most people recognise as a living hinge. A first box, tight budgets of cut time, and when you want the wood grain to show more than the pattern.

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 curved cylinder box

Is the Curved Cylinder box free to export?

Yes. The Curved Cylinder is one of the three free shapes: design it and download the SVG with no account and no card. Pro adds the other 97 shapes, 19 more hinge patterns, custom kerf and DXF.

What size can a curved cylinder 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 curved cylinder 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.
