This is my model of chicken from Minecraft. One pixel in Minecraft, corresponds(equals) to 1,5mm in real size. I printed this one with 0,15mm layer, 15% infil, without support or raft. It's higly recommended to print "minecraft_chicken_bigger_holes.stl" file, beacuse it's easier to fit parts. I recommend to print with 0.1mm or less layer for best quality. In the future, I want to make models of all minecraft creatures.
Feel free to scale my models if you need.
