Make this box About the reverse tuck carton
Folded shut and measured in 3D: the cavity is 101 × 101 × 101 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 12-inch softball: the 12 inches is the circumference, not the diameter. That gives 99 mm across and a cube carton of 101 mm.
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 softball: from a published standard or format specification.
“E. THE 12-INCH BALL: The official 12-inch softball shall be 11 7/8 – 12 1/4 inches in circumference when measured across two seams and weigh 6.50 - 7.00 ounces.”

The flat blank
- Reverse tuck (ECMA A20.20.03.01): the top closes from the back, the bottom from the front. Nests more economically on the sheet.
- The tuck flap is 0.70 mm narrower on each side than the closing panel - a full caliper plus clearance - so it slides past the side walls and the glue seam.
- Closing order: dust flaps in, closing panel over them, tuck flap behind the wall.
