There is no standard size for filament spools, especially the hole size and thickness of the spool.

This is my solution. I hope it works for you as well.

You can customize your own spool adater using the included OpenSCAD file.

You can change the

-spool hole size (make it slightly bigger for a snug fit as the spokes can bend slightly)

-spool thickness (make one long piece or two opposing pieces)

-spool holder's axle

You can make one using thingiverse'sOpen in Customizer feature or download theCustom spool hub.scad and the preset fileCustom spool hub.json. Use the free app OpenSCAD to open this file and turn on Customizer window to generate your own custom spool adapter.
