I hate supports and thought it may be helpful for others that also hate supports or have smaller printers and want to print this BIG!
I printed each piece at 250% scale on my SeeMeCNC Artemis using random leftover spools of PLA. Glue it together with your choice of glue (I like two part epoxy for the setup time) and then finish as desired!
I only used a few very easy/small supports but also may have been able to get away without them.
The tip of the nose is not a separate piece, I was just using up the orange filament and fed in some natural PLA right as the orange ran out.
EDIT: I should have oriented the STLs with the flat sides down for you, but I forgot. Sorry! You'll just need to make sure you adjust that in your slicer before you slice. (resolved)
EDIT 2: Some users were having issues rotating the models to sit flat on their print beds. I uploaded new files that are rotated correctly and ready to print!
Your choice 10-15% should be plenty.
