SUNLU Filament Spool Adapter with RFID Chip Holder

I possess numerous SUNLU filaments whose spools, unfortunately, do not perfectly fit into Creality's CFS box. To remedy this, I have designed adapter rings.
Two adapter rings precisely adjust the diameter of SUNLU filament spools to match that of Creality RFID filament rolls (200 mm), ensuring proper fit within the Creality CFS box.
Additionally, a circular RFID chip (Ø max. 25mm) can optionally be attached to the ring.
For your convenience, I have provided three variants: a neutral version, one labeled “PLA,” and one labeled “PETG.”
I tested this with a SUNLU PETG spool and a correspondingly labeled RFID chip; filament feeding and recognition worked flawlessly with the adapter rings.
For labeling the chip, I employed the app “RFID for CFS.”
