Protostars logo with a keychain. Used with Makerlabs image to keychain generator. You do not need to buy the split ring keychain from Bambu Lab, that is just added in incase you need it. I HAVE PERMISSON FROM PROTOSTAR HIMSELF. HE ASKED ME IF HE MAKES A KEYCHAIN FOR ME TO TAKE THIS DOWN. HE DOES NOT CONDONE ANY COMMERCIAL USE OF THIS MODEL AT ALL.
