Perhaps that might be a better option.

Obviously a lot quieter than my Makerbot Cupcake (most are) -
pretty funny to imagine it in a library screeching away.

As noted originally, the materials available will likely be
important for a high-strength application. The library might only
have PLA available, which would be a poor choice.
