I have not yet printed this model but I have deduced on a slicer that the best orientation for Finn's head would be on the top or bottom to be on the build platform or bed. A raft is suggested with support only needed on the lower curves of the main body. I would also suggest a 5 to 10% infill. The model was also designed to be printed at 0.2mm layers. Once I get a chance to experiement I will update the file. I have also added a 0.2mm offset to the nut and internal pieces for the bolt and main body.
