Missoula, Montana (the veritable Hub Of The World, I know... eat your heart out, Boston) has a Makerspace in its public library, has classes for it, and allows people to reserve time so staff can provide one-on-one time and troubleshooting. It's a perfect use of the space. It also has things like D&D guilds for teens and adults and something called the Democracy Project, which is apparently a civic engagement project for teens.
