Implemented simply by cutting the original in three parts in Prusaslicer and extending the middle part about 1cm. As a downside, the hexagons are now no longer perfectly symmetrical. 😢
Fits very well to the Ikea Skådis board - snug fit without coming loose (at least in my print).
The axle is quite long so it's okay that the wholes in the board don't match the length of the roll perfectly.
The author remixed this model.
