My brother-in-law is a science and electronics whiz and always up on the latest technology.  So it's no surprise that he's already into the 3D printing thing.  Last week he gave me a bunch of wargaming terrain, and this is the first of the lot: some barricades and a container.  Not too hard to paint up, and I avoided putting labels or designs on them so they won't preclude themselves from being used in lots of genres.

I have no idea how hard it was to make these--I will have to ask, but it is pretty cool that he could cobble these together using free designs off the internet and give them to me.
