Carved starred triangular cassette
The six-facet triangular star, carved into the panel: the centre sinks into a hollow, three alternate points dip halfway, ridges and valleys swap. Alternating point-up and point-down, it tiles a wall with no waste.

Fabrication data
Carved starred triangular cassette — at 700 × 606 mm in 4 mm ACM, this family unfolds into a 767.5 × 700.1 mm flat pattern with 17 folds, including 1,215 mm of groove machined from the visible face, with the sheet flipped for that pass. A 1,500 × 3,200 mm sheet holds 8 of them, for 44 % waste.

Manufacturing constraints
- The return must exceed the groove width plus half the bend deduction, or the groove eats into the return.
- Facet-to-facet folds are grooved with the smallest cutter of the profile, V left open: the angle is held by the geometry. The angle between two facets must not exceed that cutter’s apex angle.
- Vertical returns, all tabs flat in the −D plane (rail mounting). The facet-to-return fold is 90° ± slope: below 90°, the 90° cutter is left open and the return is held by the riveted tab; above 90° (facet descending towards the edge), a wider cutter (60° nominal = 120° apex) or the machine profile’s overfold tolerance is needed.
- Every raised vertex requires a V-slit to the edge (a flat sheet has 360°, the relief less). Near the vertex the slit is narrower than the contour tool: it is cut along its axis and the tool bites each facet by up to Ø/2.
- Tabs are shortened at every corner and every kink of the edge so they never collide behind the panel: by (return + 2 mm), and more on a sharp corner, where the bisector must be cleared (tab width ÷ tan(angle/2)). An edge too short gets no tab.
- The bottom of the hollow sinks BEHIND the face of the panel: it must stay at least 5 mm in front of the tab plane, otherwise the relief hits the framing and the cassette no longer sits flat on its rails. A carved star therefore needs a deeper return than a raised one.
- A V-groove is cut on the CONCAVE side of the fold. Carved, the star reverses its folds: what was a ridge becomes a valley and goes on the RAINURE_AVANT_* layer, machined face up with the sheet flipped; former valleys, returns and tabs are grooved from the back.
- Alternate points stay shallower than the bottom (by at least 10 mm) and close enough to the face for the bottom to remain a backward peak (angle sum < 360°): a deeper dip is brought back to the limit.
