Models
Each of these is a short KerfScript program. The pictures are rendered from the source when the site is built, so what you see is what the file cuts. Open one to read the code, change its settings in the playground, or download the cut file.
Finger-jointed box
Finger-jointed box with a lid.
Spur gear pair
A pair of spur gears with involute teeth, cut from one sheet.
Jigsaw puzzle
A jigsaw puzzle. Every edge between two pieces gets a knob that points one way or the other, picked by the seed.
Clock face
A clock face: cut outline, scored minute marks, engraved hours.
Snowflake ornament
A six-armed snowflake ornament. Each arm is one branch, repeated.
Slot-together phone stand
A phone stand from three parts that slot together without glue. The slots follow the sheet thickness, so changing it keeps the fit.
Guilloche coaster
A round coaster with a guilloche pattern: the same wavy ring drawn several times, each copy shifted a little, so the lines weave.
Sunflower lamp panel
A lamp panel with holes on a sunflower spiral. Every hole sits at the golden angle from the one before, which packs them evenly.
Honeycomb trivet
A hexagonal trivet with a honeycomb of hexagon holes.
Engraved ruler
A ruler with scored millimetre ticks and engraved numbers.
Living hinge card
Card with a living hinge down the middle and a scored fold guide.
Name sign
Name sign: plate sized to the text, with two hanging holes.
Calibration square
A 100 mm square with a 20 mm hole, for checking size and kerf. Measure both after cutting. If the square is small and the hole is big, raise $kerf by the difference; if it is the other way round, lower it.
Kerf and fit test
Slots from a little narrower to a little wider than the material. Push a scrap of the same sheet into each slot: if the one marked 0 is snug, $kerf and $thickness are right. If a + slot fits best, your material is thicker than you said; if a - slot does, it is thinner.
