How this one is built
- Slot closure: the tabs on the lid flap pass through the front wall. Slot height = 1.90 mm (caliper plus clearance).
- Folding order: 1) front and back wall up. 2) dust flaps in. 3) side wall up, over the roll bridge, inner wall down. 4) push the tongues at the foot of the inner wall straight into the slots in the base. 5) close the lid.
- Roll bridge = 3.40 mm: 1 layer(s) of 1.5 mm plus 0.40 mm clearance.
- Front and back wall are inset 1.50 mm at both ends so they fall inside the ear plane. Without that set-back the lid ear runs straight into the front wall.
- The inner wall ends in 2 tongues per side that go straight into slots in the base - no folded-over tab, so the roll has no reverse crease and the sheet never needs turning.
