While traveling through the internets, (yes there’s more than one)
I came across a service called shapeways, that will print 3d models for you,
They have some neat stuff, and anyone can create their own models and upload them.
(Link to shapeways)(Supported software)(And the Blender tutorial that led me to the site)I don't mean for this to sound like an ad or anything, I just figured that there would be a lot of interest in something like this, so there you go.
EDIT----
Some links were old and broken so I fixed them.
