I tried some other cardboard spool rims here but they suck - they slip off too easily. I designed one with a lip to greatly reduce the odds of the rim slipping off while printing. Tested on ELEGOO Rapid PETG and PLA+ cardboard spools (which are 199mm diameter) and this rim works great!
This should work with any ~200mm cardboard spools (there is some tolerance built-in) where the cardboard sides are approximately 3mm or less in thickness. I also uploaded the original Fusion 3D f3d file, so you can adjust the parameters to change the various dimensions of the rim, if you need to do that to make it fit your spools better.
Prints without supports.
