What's in the download

Seven pieces, one purchase

BODY

Finger-joint body

Bottom + 4 walls, every seam kerf-compensated so tabs and slots come out to nominal size after cutting — a real friction fit, not a guess.

LID_CAP

Lid cap

A flat cap cut to your box’s outer footprint, sitting flush on top.

LID_SKIRT

Lid skirt

Glues to the underside of the cap, sized to your interior opening minus kerf, so it plugs in and holds the lid centered.

How it works

Three numbers

Your interior dimensions, your material thickness, and your kerf. Already ran the Calibration Toolkit's kerf test? Use that exact number — every joint is sized around it, so the fit is measured, not guessed.

Stop rounding to the nearest size. Build the exact box.

Sized to your material. Instant download, unlimited regenerations, forever.
