About the BoxHeart generator
BoxHeart builds a heart shaped box out of straight wall segments that follow the heart outline, so it cuts cleanly on any laser and glues up like a segmented ring. The base and lid are single heart shaped plates with slots for the wall tabs.
What you can adjust
Outside or inside measurements, so the box fits the space — or the contents.
Material thickness from presets or a custom value, plus your machine's kerf.
Finger joints or flat, glued edges, with a target tooth width you can change.
A 3D preview you can spin, and a flat cutting plan with every panel named.
How it goes together
The heart outline is split into wall segments held by the base and the lid. Because the segments are straight, the outer seams open by a fraction of a millimetre — run a bead of glue down each seam while the box is assembled.
Tips for a clean cut
The lid cut-out is meant for thinner material: on 4 mm ply a large lace pattern can get fragile. Keep at least 3 mm of material around every cut.
Frequently asked questions
Can I work in inches or centimeters?
Yes. Switch between mm, cm and inches at the top of the panel. Material thickness and kerf are always entered in millimeters.
Which file formats can I download?
SVG, PDF and DXF — all at 1:1 scale, in millimeters. AI files read the SVG or DXF straight into Illustrator.
What does the “Try other dimensions” button do?
It fills in a different set of measurements so you can see how the design changes before you enter your own.
