It's probably worth noting the libraries I've seen that have a nice makerlab (to where the the tools are maintained and they facilitate trainings) usually have at least a couple staff librarians that are fairly enthusiastic about making things and using the tools themselves too. That's my limited anecdotal experience, noticing there's also been libraries that might've initially offered 3d printing then stopped (possibly due to abuse, maintenance burden, staff changes, etc.)
