Your fully variable Master Spool comes here. (Please read all before printing!)

This spool is built of 3 different files, ending up with 8 parts (there is one optional part):

Spool half with external thread (Spool w external thread.stl)	print 1x
Spool half with internal thread (Spool w internal thread.stl)	print 1x
Spacer (Spacer.stl)	print 6x
Filament clip (Filament clip.stl) -> Optinal!	print 1x

The other stl files are for tinkering you don't need them for a Master Spool!

The model provided will generate a Master Spool with for a refill with an inner diameter of 82 mm. If you need a different diameter you can either reach out to me and I create the spacer on request or you can create them on your own. If you are able to create them on your own, follow the geomety shown in the PDF. You just need to change the radius R41 to the size you require.

Following an additional explanation for those, who want to re-work or adjust the files (Step files available as well):
I also include the whole Freecad File for tinkering. Be aware that i ended up with a non-manifold Spool with internal thread.stl (if somebody finds a solution for it, I appreciate if you get in touch with me). I fixed this by exporting the Side panel w sticker surface.stl and Core for slicer use only.stl separately and upload both of them into the slicer and print afterwards.

If you like this design, please post your print with a picture.
