I remixed this add appropriately sized spots to stick the RFID tags to for those of us using custom RFID tags on the K2 Plus. This version has NO nub on it for the bambu spooless filament. They work great for Elegoo spools, and I add a rubberband on each side to make a tighter grip. They also work well when using a respooler.

Added place to put the RFID sticker
