This is a keychain version of McGybeer's Articulated Lizard V2. His models are great and I have been printing them for years. He is an excellent creator to support.
This keychain only uses 4g of filament and is a great option for your roll ends. It prints well and maintains all of its articulations at least on my Mark 4. I have collection of keychains which include more of McGybeer's designs if that is more up your alley.
The author remixed this model.
Scaled and added the ring for attaching your keys.
