I created a tool for a 25mm rfid tag for Creality CFS and then a holder and a cover with a small area to be easily removed and reused.
They must be mounted on both sides. It doesn't matter if they are symmetrical, just use the tool to respect a distance from the edge of the filament roll, exactly 25 mm.
