3-D printer at the Martin Luther King Jr.  Memorial Library in Washington, D.C. (Andrea Peterson/Washington Post)

The Switch recently stopped by our local library, the Martin Luther King Jr. Memorial Library in Washington, D.C., to check out its new 3-D printer, but didn't have time to see it in action.

Obviously, we need to change that. We might not be ready to print out a working Aston Martin, but we have a few ideas. Vote below to help us decide what we want to print!
