Some users solve the issues of cardboard spools by using black plastic tape or adapters. I've created adapters for Eryone brand spools using PLA HS filament, adding an aesthetic touch that includes a container for bags or silica gel beads. The adapters are assembled with 4 brass M3xH4xD4.2 threaded inserts and 4 M3x10 screws. I plan to create more for different spool brands. Here's the link for filament settings. Thank you
