Filament ring for Polymaker + 3D Printing Canada

I wanted a filament ring for my Polymaker and 3D Printing Canada cardboard spools. This is particularly useful if you plan on using the spool in AMS. In my case, I wanted the additional protection due to the way I store the spools in a dry box. I couldn't find any existing models that fit well, so I resized the Elegoo filament ring to fit snugly on my Polymaker and 3D Printing Canada rolls. I figured this might also be of use to others. The ring still features the Elegoo infinity symbol, but it's pretty innocuous and allows for consistency in my filament library. Tested on Budget PLA from 3D Printing Canada. If it doesn't fit your spool and you would like me to add additional sizes, let me know the precise diameter of your spool.
