Box Divider Designer
Create interlocking cross-lap dividers that form a grid inside your box. X and Y dividers get half-depth slots and simply slide into each other.
Cross-lap joints
X dividers are slotted from the top, Y dividers from the bottom – they slide together without glue.
Flexible grid
Configure any number of dividers in the X and Y direction. The compartments are divided evenly and automatically.
A perfect fit for your box
Enter the inside dimensions of your box and the dividers are generated to fit exactly – with kerf compensation.
Tips for box dividers
- Material thickness: 3–6 mm plywood or MDF works best. Thinner material can become unstable with many compartments.
- Kerf compensation: The slots are widened by the cut width so the dividers fit snugly. Typical laser values are 0.1–0.2 mm.
- Test cut: Cut a 1×1 divider test first to check the fit of the slots.
- Assembly: Insert all Y dividers into one X divider first, then push the remaining X dividers on from above.
