A set of old steam radiators. Although there is only one in the picture, the model has 12. It is designed to print in FUD.
The pipe that leads to the floor will be a little bigger than the picture (.8 scale inches bigger in diameter). Although the model obviously prints OK, Shapeways wanted a change.
All models arrive unpainted shipped direct from Shapeways. Most have to be cleaned prior to painting. You can get more information at my website: Dave's Model Railway Stuff (www.davesmrs.com)
