Sure, now the original dimension will fit all (that I have tested) 1kg filaments. If you need larger diameter (some 2kg spools are only wider, not larger in diameter), you will need a slightly taller filament room, which is very simple to add just by extending vertical beams for 50 or 100mm or some custom dimension. You also need to apply that new dimension for all 4 panels that are around filament room.
No problem and Happy New Year to you too! :) :)
