This is a game model I ripped out of Risk of Rain 2, I thickened the super thin parts and generally made the model more printable.
I printed the whole model with the 0.2mm speed preset in generic "silk blue" PLA.
Body
Flip him on his back and print that way, it'll use way fewer supports that way. The legs need additional support so you can enable it everywhere. Depending on your settings that may generate a little too much support so you can use enforcers to limit that to only the bottom and the back legs.
Head
Place the flat side on the bed and print using supports only from the build plate
Pin
It's a rectangle, not that hard to print
