This is a Bokoblin, from Legend of Zelda Breath of the Wild. It was a fun challenge to model this, but I enjoyed the process. I already put the model through a software that fixes 3D models, so you should have no problems if your print settings are good. I would recommend a .1 mm layer height to help capture all of the details in this model.
I designed this model using a free program called Sculptris. If you would like to try out this program you can download it here: http://pixologic.com/sculptris/
