Set of panels and an associated assembled article

A set of panels comprising a first panel and a second panel configured to assume a locked state in which a first main plane of the first panel is arranged at an angle (ϕ) of between 30° and 150°, relative to a second main plane of the second panel, the set comprising:

• a groove provided in the first panel,
• an edge section of the second panel,
• an insertion groove provided in the groove of the first panel, a separate tongue being arranged in the insertion groove, and
• a recess provided in the edge section of the second panel,
• wherein the separate tongue is configured to cooperate with a locking portion of the recess for locking the first and second panels to each other in a first direction perpendicular to the first main plane,
• wherein the edge section of the second panel is configured to cooperate with the groove of the first panel for locking the first and second panels to each other in a second direction parallel to the first main plane and extending towards a side edge surface of the first panel, and
• wherein the locking portion is disposed at a locking angle with respect to the first direction, the locking angle (α) not exceeding 40°.
