200mm/178mm Filament Spools (Large/small Diameter 1kg)

This is a render of a 200mm and a 178mm Diameter filament spool for designing spool holders and storage systems. These are common "Ebay" spools that I have found so far.

These two spools have different center diameters, widths, and outside diameters which is difficult to make a universal filament holder.
