Guide & tips

Stackable Box Designer

Create open-top boxes with a built-in stacking mechanism. The bottom panel is raised so that recesses along the bottom edge and tabs along the top edge of the side walls interlock when you stack the boxes – no extra hardware.

Stacking mechanism

Stacking tabs on top and recesses at the bottom with 30° chamfers guide the boxes into place and lock them securely when stacked.

Raised bottom

The bottom panel sits raised inside the box, leaving room for the stacking mechanism underneath.

Optional handle cutouts

Rounded handle cutouts on the short sides make the boxes easy to carry, even when full.

Tips for stackable boxes

Material thickness: 4–6 mm plywood works best. Thinner material can become unstable once several boxes are stacked.
Stacking mechanism: The height of the stacking tabs matches the material thickness. The safety margin to the bottom panel keeps the boxes from slipping.
Handle cutouts: Placed on the short sides by default. Make them at least 60 mm wide for a comfortable grip.
Test cut: Cut a small test box first to check the fit of the finger joints and the stacking tabs.
