A laser-cut Compartment Organizer Tray combines a 5-panel finger-jointed open tray (Base, Front, Back, Left, Right) with internal interlocking half-lap slotted partitions (Longitudinal X-Divider and Transverse Y-Divider) to create a rigid 4-compartment grid without screws or brackets. For the cross-dividers to slide together flush at the center intersection without wobbling or splitting the plywood, the half-lap vertical slot width must equal exact material thickness minus laser kerf (W_slot = T - K). Our generator outputs all 7 precision plates nested on a single 1:1 .DXF, .SVG, and .PDF sheet.

Mathematical Blank & Tolerance Formulas
Subtracts laser beam kerf (K) from nominal sheet thickness (T) so the longitudinal and transverse dividers lock together with a snug friction fit.
Sets the internal partition height flush with the top rim of the outer tray walls.
One divider is slotted halfway down from the top edge and the mating divider is slotted halfway up from the bottom edge so their top edges sit 100% flush.
Step-by-Step Export & Assembly Guide
- 1 Measure your exact sheet thickness with digital calipers and enter L, W, H, Thickness (T), and Laser Kerf (K).
- 2 Inspect the 7 nested parts in the 2D CAD view: Base Plate, 4 Finger-Jointed Outer Walls, Longitudinal X-Divider (top-slotted), and Transverse Y-Divider (bottom-slotted).
- 3 Preview the assembled tray and internal cross-partitions in the 3D Fold Preview tab.
- 4 Export as 1:1 .DXF or .SVG, cut the 7 parts, assemble the outer finger-jointed tray, and slide the Y-Divider downward into the X-Divider half-lap slot.

Frequently Asked Questions — Compartment Divider Tray (2×2)
How do the two internal dividers lock together at the center?
They use a classic woodworking half-lap cross joint: the longitudinal X-Divider has a vertical slot cut halfway down from its top edge, while the transverse Y-Divider has a vertical slot cut halfway up from its bottom edge. When slid together, both dividers lock at 90 degrees with their top and bottom edges completely flush.
Why is the half-lap slot width slightly narrower than my material thickness?
When a laser cuts an internal slot, the width of the laser beam (kerf K) widens the cutout. By setting the CAD slot width to (T - K), the physical laser-cut slot finishes at exactly T millimeters for a tight, rattle-free fit.
Can I remove the internal dividers if I want a larger compartment?
Yes! Because the internal X and Y dividers sit inside the outer finger-jointed tray, you can leave the cross-dividers unglued so they can be lifted out or reconfigured anytime.
Are all 7 parts exported as closed vector polylines?
Yes, every single tray wall and slotted divider is exported as a 100% closed, non-overlapping LWPOLYLINE on the CUT layer.
