About this 3D model
This is a Smurf house. Except roof, you can print them without support. MainBody and Window has designed support which should be removed after print. I tried to separate colors. And it makes it little bit difficult to assemble. This will help you to figure out how to assemble them : https://a360.co/2JvHsr7 I printed them with 0.2 ~ 0.24 layer height. with 10~30% infill and 2 walls.
