It sounds like a really interesting idea. I think we will start to see more and more 3D Printing shops pop up all around Europe and the US. There are already MakerBot stores in the US in 3 location. What I think is needed is a shop that carries a great range of 3D Printers, from all the companies including some of the smaller ones. I would think these smaller brand companies would be well willing to provide shops with free floor models to get them off the ground. Wish I could help, but being in the US would make things very difficult
