I have printed this (great!) spool holder, but I had some “Recycled PLA” refill, which is completely loose when installed in that holder:

So I quickly designed this spacer:

Whose internal diameter is 81mm and the external one 99mm.

I guess I could have made it smaller, as it has printed in near 2h using an Ender KE.

I made that “I” shape to save filament and weight, as the reel would sit on the external sides of the spacer.

The height is 59mm between flat faces.

Once I printed I can say it feels quite hard to install.

There is a v2 of ~57mm height and 83-97 diameters, but note the one I printed is the v1 and it works. I don't know why, but Fusion360 did not allow me to create 1mm chamfers, so I did a 0,4mm ones instead.
