To print this model, I chose Shapeways for faster service and a slightly better price. The model arrived in about two weeks, and I could not be happier with how it turned out. The finish is somewhat rough, like a sugar cube. The colors are bright and vibrant, but I'm especially pleased with how the window grills look in the following two images:

In the following image, you can see the crisp detail of the ridge seating the base of the roof to the walls. The fit is excellent, and makes the cabin look like one piece when in place:

It's nice to place an order and get back a perfect model, printed by professionals. This approach allows you as a designer to focus on making models rather than troubleshooting failed prints. Of course, if you like the challenge of operating a 3D printer, there is nothing wrong with that!
