Check out my Petreon page for a nice Warhammer file.
General terrain? A wind Farm? For 28mm Scale?
A big building or tower? For 6mm Scale?
Whatever, it is there to print at any scale or rescale to suit your own needs, a big model for your table and should look good when painted up.
Too expensive via Shapeways.

I purchased a few books of interest, sacred geometry, golden section, and one on compass and ruler exercises.
I really love the sacred geometry styled Gothic church windows. I have designed some in CAD and shall print some off with the hope that they make nice details for MDF type laser cut buildings for war gaming.
Also available on my Shapeways shop.
Here's one to look at; set of 4 windows works out as a good price.
Designed some ruins / scatter terrain in 28mm scale. A ruin of an old Star Gate and a Column Base; no real purpose but should look good to dress the table.
