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.

Structural Geometry & Material Reference (Symmetric Odd-Harmonic Finger Joint + Half-Lap Cross-Slot Standard)

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.

Half-Lap Interlocking Divider Slot Width (W_slot)

W_slot = max(0.8 mm, T - K)

Subtracts laser beam kerf (K) from nominal sheet thickness (T) so the longitudinal and transverse dividers lock together with a snug friction fit.

Internal Divider Plate Height (H_div)

H_div = H - T

Sets the internal partition height flush with the top rim of the outer tray walls.

Half-Lap Slot Depth (D_slot)

D_slot = 0.50 * (H - T)

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.
