Tested with cardboard spools from:
It should also be fine with cardboard spools from other filament vendors including:
Please let me know if it works with spools from other vendors, or needs to be scaled for spools from other vendors.
I suggest printing in PETG for spools of low temperature filaments (PLA etc) and ASA or ABS for higher temperature filaments, so that you can leave the spool rings on when you dry a spool. PLA works fine, but may shrink and distort when in a filament dryer over time.
After attaching each ring, check that the inside edge of the spool is sitting inside the ring. If it won't pop into place (normally because the edge of the cardboard is damaged) then run the wide part of a flat blade screwdriver around the edge of the inside of the spool to push the cardboard into place.
