You can download the spool holder here https://github.com/seemecnc/PrintableStuff/tree/master/SeeMeRollinPrintableSpoolHolder
This base clips in between the openings on the bottom to keep them the correct distance. Note these don't move on their own but when I would change spools I would always knock one out of alignment hopefully this will resolve it.

Will fit a standard width 1KG spool, should be easy to remix and make larger
Seems as though there many variations even in the 1KG spools so I have included the Fusion 360 file to allow for easier adjustments
