A running gag on the internet is to imagine what the body of moai's looks like. While archeology has already answered the question, in an alternative universe they might be musular. I saw some illustrations in the past but no 3d printable model so here is one. May he inspire you to become stronger!
I also provided a previous step of my building process, namely the musular body without any head. It might be useful would you want to remix the muscular body.
Printing information:
All credits go to the original authors of both base models as my intervention was really insignificant.
Note that I had to comply with the license of the moai head and that the licence of this model is therefore also non-commercial. Would I have had the choice, only attribution would be required.
The author remixed this model.
I combined both models into one statue
