How hard is it come up with community run maker spaces supported by the city for putting such things together? Not every thing has to be owned by large private companies.
As someone who works with a non profit who does this… don’t ask the city, they rarely care about thing’s like this. They will talk about support, but it’s talk. Most are too involved with crazy politics, campaigning, etc. Better to seek out other non-profits and community services to work with.
Libraries are a good starting point for your idea, but they are already being defunded.
