Reusable cardboard spool adapter for Bambu refill

https://i.redd.it/6yxug6uwunhe1.gif

Ordered Bambu refills and had a few Elegoo cardboard spools. Came up with this solution in order to save plastic and time instead of printing a full spool (77g - 0.24mm layer; 78g - 0.20mm layer).

Maybe someone saw or designed "Low Friction Spool Holder" that could allow to mount a spool with 41mm hole if not, might try to design one myself.
