Support for filament rolls.

"UPDATE: The files have been modified to be able to create a third floor" Shelf for our filament rolls, with an interior width of 75 mm, suitable for the thickest rolls, it is printed WITHOUT SUPPORTS in a very simple way, when joining the pieces it is super compact, even without glue (I recommend using glue to join the pieces), in addition with each module that is added the structure is much more reinforced, practically unbreakable with very little filament necessary. We can add infinite modules, either 1, 2 or 3 floors, the top floor is capable of supporting many Kg without problem. The design allows us to insert our hand to be able to release or pick up the filament without colliding with anything. I also designed a label for each support, this way if we have two rolls of the same color and different material, we can quickly and easily know which material we are looking for.
