About the SlipTop generator
SlipTop builds the box and a shallow tray that slips over it. The lid is a plate with slots and four low walls, so it lifts off cleanly and stacks flat between the contents.
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 tray walls tab into the cover plate and glue at the corners. The total gap is how much larger the cover is than the box: 0.6 mm on a 3 mm sheet is usually right, and you can open it up for material that swells.
Tips for a clean cut
Measure your sheet with calipers before you cut: material sold as 3 mm is often a little thicker or thinner, and that changes how tight the joints feel. Enter the kerf you measured on your own machine. If the first box is too tight or too loose, adjust the kerf in small steps and test again on scrap.
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.
