From their post:
Another box of goodies arrived at Brigade Towers the other day, containing test prints of more items for our Shapeways shop. These looked good, so they're all available to buy now. Once again, these are items that would be tricky for us to produce by traditional means in metal/resin. All of the items are 6mm, and include some rather neat power pylons (in one piece… how's that for ease of assembly!) and a small power station cooling tower, which came about as the result of a request over on the 6mm_Minis Yahoo! Group.
