This is used to convert your 1" blade diameter Xenopixel v3 core into an Baselit-RGB V3 saber. Please note that this upgrade is exclusively compatible with Xenopixel v3 cores and specific saber models. Not all sabers can be upgraded, and assembly is essential. Make sure you have an empty Baselit-RGB V3-designed blade for this enhancement; Neopixel blades are not compatible.
