Filament spool holder

Since i'm about to receive my Pallete2 i need 4 spool holders in order to make effective use of it. I searched for something to my liking but i couldn't find anything that fully met my needs.

I want to place the spool holders next to each other on a base.
I want to be able to use a variety of spools with different inner diameters without having to use different stuff to accommodate for that.
I want to use the spool holder such that it can be placed either next to the printer or on a lower level below the printer, without having to worry that the spool detaches from the holder.
I want to be able to easily replace an empty spool, just by pulling it out of the holder, replace the empty spool with a full one and putting it back in.
And lastly, i want the spool holder to be fully 3d printed without the need for any additional material.

I came up with this design. It can accommodate for spools with an inner diameter of 35mm up to 55mm and outer diameter of 200mm up to 355mm. Sp
