Pharah from Overwatch. Completed model stands over 16 cm tall with an 8 cm diameter base, and should easily scale up.
This model was created using Source Filmmaker assets, pulled into Blender. It was then rigged and posed to optimize for 3D printing.
I provided both the full model and a version split at Pharah's waist. I highly recommend printing Pharah_Upper, Pharah_Lower, and Pharah_Tips instead of Pharah_Full. Pharah_Full has not been tested and would be a very difficult print, even with good support. The base with the Overwatch logo will work with either configuration.
Sliced on Cura 2.3
Be very careful with your support settings. Although I have made sure there aren't floating parts, I cannot make any guarantees that I found them all. There may be sections that are impossible to print without custom support.
