Grr Argh Keychain

I'm a huge Buffy fan so wanted to make something for it. There are two models on the build plate. One is for a screw in chain end and the other is for a jump ring chain. I got mine from Amazon and they can be either. https://www.amazon.com/dp/B07CSM96JP?ref=ppx_yo2ov_dt_b_product_details&th=1
