Spool ring R3D filament

I have already used cardboard spools but this is only if I have to print 1 color.

Ordered this brand because I needed this exact color for a multicolor print.
Spools of R3D are Ø195 so this already didn't fit. (I made the outside diameter 200mm)
 

the spool was also not 100% round.
So I didn't trust it when I had to do 600 color changes.
I have made clips that the ring does not come off the spool during printing.
