Guinea Pig 2d model suitable to your keychain.
Printed on Prusa MK3s+ from black PLA with resolution 0.2.
One Guinea Pig takes approximately 48 minutes to print.
The author remixed this model.
I added at the top of the Guinea Pig a small ring to attach to the keys.
Personally for me is better to have it like that, because the ring attached to the keychain does not disturb the visual of the model that much.
Now you can have a Guinea Pig with you everywhere!
