As You can on the picture I have 2 very large filament spools, and experiments with spoolholder-"feets" with 4 ballbearings gave too much friction.
This model have holders for 2 different sizes of large filamentspools: 52mm inner diameter and 105mm inner diameter. - Do You have rolls with another diameter, You can create some holders and change them whenever You feel like it!
In the middle of the center spool You put a 22mm ball bearing - in each end. And the rod holding it all is a 6mm threaded rod. - The stand is a little thin for a 5kilo role, but its strong enough for printing!
The stl files contains one of each component, so You have to duplicate them in the slicer!
