Flap gap
Gap between adjacent flaps or walls; at least approximately material thickness.
Folding cartons and inserts / JETDIELINE
Lower part of the telescopic box made from folding carton board: base with four walls and glued corner flaps, same design as the corrugated telescopic box, for smaller gift and chocolate boxes.

carton.telescope.baseThis template is a component of a packaging assembly. Match its dimensions to the other parts; lids, bases, wraps and linings serve different purposes.
Base and lid each consist of a tray with four walls and glued corner flaps. Both components are separate templates. Their relationship is established through the base's outside dimension and lid clearance.
Base: erect front and back walls, fold corner flaps inwards, erect end walls and glue them to the corner flaps. Lid: erect front and back walls, fold corner flaps inwards, erect end walls and glue them to the corner flaps. Place the lid upside down over the base.
Test fit, folding and closure on a sample made from the intended material. Confirm material thickness, grain direction and production steps with your printer.
Inside dimension
These dimensions describe the preview, not a fixed packaging size. The app recalculates the dieline for your own dimensions.
Gap between adjacent flaps or walls; at least approximately material thickness.
Length of ears or corner flaps as a proportion of half the inside width.
The lid needs the base's outside dimension plus clearance on each side. The base's inside dimension alone is insufficient: the dimension model accounts for material thickness. The documented individual starting examples are base 150 × 100 × 50 mm and lid 154 × 103 × 20 mm. The lid starting dimensions are rounded; confirm the fit of both parts on a joint sample.
Identical inside dimensions do not produce a fitting telescopic joint because the base walls require additional space outside. Determine the lid from the calculated outside dimension of the lower part and the chosen clearance. Coating or corner gluing can also affect practical fit. Check fitting and removing the lid with both real parts.
The flap gap leaves space between corner flap and adjacent wall. Ear length determines the extent of the corner flaps as a proportion. Both parts use these parameters with their own dimensions. Ears that are too short provide insufficient glue width; too large a gap does not suit the wall height. The tables show each component's unchanged starting values.
