Make this box About the cake box with window

Folded shut and measured in 3D: the cavity is 132 × 132 × 66.5 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

Four muffins, 2 by 2. The cup is 51 mm across and 32 mm deep, but a baked muffin rises and spreads over the edge, so each muffin gets 66 mm of room and 35 mm above the cup.

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

Four muffins: from the manufacturer's published specification.
