Make this box About the cake box with window

Folded shut and measured in 3D: the cavity is 241 × 241 × 55.5 mm and the product block fits without touching the board. Free to open and change; €2.50 for the PDF, €3.50 for the DXF or SVG.

Why these numbers

A 9-inch pie plate is usually 1.25 inches deep, deep-dish plates up to 2 inches; the box is 57 mm high inside so both fit.

Food. If the food touches the board, ask your board supplier for food-contact grade board. The drawing sets the shape; it does not make the board food-safe.

Every size on this page is an example to start from. Products change between models, editions and makers, so measure the one you are packing.

Where the product size comes from

A 9-inch pie: from a general reference site, not the manufacturer.
