3D Printed Dual Spin

I'm currently trying to design a 3D part for dual spin layers, but I'm having some trouble. I'd like if someone like Xandork can give me the design they used for Jojo's Jynx Ouroboros. I've tried unscrewing my lS, and just planning on using the dual spin part out of that, but I'm still having trouble. If someone can give me an stl. file for a dual spin part AND the part it holds onto, I'd appreciate it. (None of this probably makes any sense)
I bought a fake Sr just to learn about how the dual spin worked, I think if somebody could make a teeth model and 2 base part models then it may be possible
