This is a small house design with a roof that fits on top. I like the fact that architectural models can be printed in such a way that you can open up the model and have a look inside, while also incorporating two colours when you have only one extruder. This is a very simple model as it is my first ever 3D design. The house was printed at 0.15mm (with support) @ 22% infill and the roof at 0.2mm @ 15% infill in PLA.
