This is a 3 part model of a 15mm scale desert house for use in tabletop/wargame hobbies. The house is designed to open up for miniatures or other small objects to be placed inside.
Print one each of a, b and c.
The pictures of my print show it after being sprayed with a coat rustoleum textured paint. Unless you like wasting your money on paint that clogs after its first use, I don't recommend it.
