i'm currently 3d printing a dranzer energy layer. but is 3d printed beyblade parts in burst cominations are tournament legal?

No, they are not legal. Only official Takara Tomy, Hasbro, or Youngtoys products. Fakes ain't allowed either

Beyblade Burst is cool, I once made a continuation of MFB, but I stopped, but now I've restarted (Then stopped again). Geist Fafnir is also pretty cool
