Main Street 5 is really easy to print and assemble. There are no 45° corners to struggle to get aligned. The side walls slip into a groove in the front and back walls, and the roof fits into a groove in the front wall. I am running out of space on my layout so if you are looking for something for yours, let me. kabrumble@comcast.net
All of my models are free, and tips are not necessary...but they are fun.
