A simple rim that clips around the outside cardboard spools. Print 2 of these, one for each side. I found that this substantially reduces friction for spools to roll smoothly, resulting in more consistent extrusion.
I would recommend printing this in something more heat resistant than PLA to prevent the rims deforming when drying the filament spool under heat.
Diameters:
Kiwifil 1Kg = 200mm
Kiwifil 250g = 160mm
If you need a different diameter spool rim let me know in the comments and I can make an STL.
