Your thinking of the Idealab on the 4th floor. Its behind the computer lab against the back wall in its own private room. Its a seriously awesome resource offered by the library. There is always an atyendant to help with projects... They have a 3D printer, Macbooks, Adobe Suite, sewing machine, etc. Hours are weird though, so check the website before going.
Seriously...smell is bad
The fourth floor is where they have the public computers and a few computer lab type study rooms. There's also a "movie room" if you can get over the smell.
