Logic Masters Deutschland e.V.

This is the third puzzle in my 'Neighbour Series'.

This puzzle is for all the solvers, who found the previous puzzles in the series too easy.
It also features a bit more varied logic than usual.
Good Luck.

Rules:

Place the digits 1 to 9 once each in every row and column of the grid and once each into the circles of the cube.

Reserved Neighbours: Digits in the grid may only be orthogonally adjacent, if they share an edge on the cube. (Eg. If R1C1 contained a 1, and R1C2 a 2, then 1 and 2 would need to be connected on the cube, for example in R10C13 and R11C14.)

Arrows: Digits along an arrow sum to the number in the attached circle. Cells outside the grid are empty and do not count towards that sum.

Killer Cages: Digits cannot repeat within a cage.
