The largest piece is 246mm in length. 
The main body was printed at a .25mm layer height.
The rest of the pieces were printed .2mm layer height. 

Models do not load in the correct print orientation.
For the main body, place “face” side up laying flat. Supports are not needed for arms/legs/stand slot but may help. 
For the other parts, just lay them flat on the bed. 

Each part is meant to friction fit into its respective holes, but this may be a printer-to-printer basis. Super glue or your choice of adhesive will help the parts stay in place.
