1. A set comprising a first panel with a first main plane, a first edge surface and a first panel surface, and a second panel with a second main plane, a second edge surface and a second panel surface, and a mechanical locking device with a junction plane (J), wherein the mechanical locking device is configured for locking the first edge surface of the first panel to the second edge surface of the second panel at the junction plane (J), wherein the first main plane is essentially perpendicular to the second main plane and the junction plane (J) is extending at a first angle (α) to the first main plane,
wherein the mechanical locking device comprises at least two rod-shaped elements at the first edge surface and at least two insertion grooves at the second edge surface,
wherein the at least two rod-shaped elements are configured to be inserted into the insertion grooves in a locked position of the first and second panels,
wherein the at least two rod-shaped elements extend at a second angle (β) from the first edge surface,
wherein the insertion grooves extend into the second edge surface at a third angle (γ) from the second edge surface,
wherein the mechanical locking device further comprises at least one locking groove at the first edge surface or at the second edge surface and at least one locking part arranged in a locking part groove at the other of said first or second edge surface, wherein the locking part is resiliently retractable into the locking part groove and is biased to outwardly extend from the locking part groove, wherein the locking groove comprises at least one locking surface extending at a fourth angle (δ) from the first edge surface or from the second edge surface, the locking part is configured to be inserted into the locking groove and lock against the locking surface in the locked position, and the second angle (β) is different than the fourth angle (δ),
wherein the first angle (α) between the junction plane (J) and the first main plane is about 45°,
wherein the second angle (β) is within the range of about 30° to 60°, and
wherein the mechanical locking device is configured to obtain the locked position by displacing the first panel relative the second panel in an assembly direction (AD), which is essentially parallel with the first panel surface and essentially parallel to a length direction (L) and/or axial direction (CA) of the at least two rod-shaped elements, wherein an end surface of the locking part is slid along the first or second edge surface while sliding the rod-shaped elements into the insertion grooves such that the locking part is resiliently retracted into the locking part groove until the locking part springs into the locking groove in the locked position.
