This is my version of Godzilla. This model prints with no supports and even no infill! This was modeled in ZBrush. The print in the pictures was printed on the Prusa MK3 with Prusament Galaxy Black.

I've also included a multi color version if you'd like to have the spikes be a different color. Godzilla.stl is the main file. The "Body" and "Spikes" files are the multi color ones.
