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.
