FIRST OF ALL: the model is not mine, I found the STL (probably a scan) on internet, I found it under many alias, so I do not put here any, if you recognize that it is yours, please let me know I put your name and link.
It could be printed without any support except for the back-pack, so I added localized supports in meshmixer.
you can download both the original stl and the one with supports.
I printed slicing it with Cura at 0.16 but using also the adaptive layers (it improves the quality for me, my settings are max variations 0.04 and step 0.01 all other by defaults [this means the resolution can go from 0.12 to 0.2]).
I hope you like it ;)
