Nikolai Mamashev published two blender models (rigs), both models are available for free to download and use under the terms of Creative Commons Attribution 4.0 license ( it's behind a Pay-what-you-want service, please support is work ).
I really like the style and simplification done with his design style. I think the volumes works really well together for 3D or dynamic animations. His work can also be used as a model-sheet to build a 3D model. Thanks him for sharing the result in a permissive license!
If you want to know more, check the interview of Nikolai published on the friendly blog of the Morevna project.
