This won't be an option for everyone. I have to travel for an hour each way to get to mine, but it's worth it. If I had more energy I would start one in the city where I live.
By the time the maker movement collapsed, it was people grinding out crap to sell on Etsy, "hand made" on a CNC laser cutter. High school students doing the maker thing to get it on their college resume. Printing trinkets with a 3D printer. Classes for teenagers where everybody built kits. Arts and crafts at the advanced kindergarten paper folding level.
I've had the urge/idea to start a maker space in the Los Angeles area on and off for years. My motivation isn't as much as a source for social engagement as much as starting to lay out a path to retirement that will have me busy at a lower level of intensity. My work does have me engaging with thousands of people every year through trade shows and sometimes a dozen trips every year both nationally and internationally.
I own enough equipment to start a very nice maker space with nearly zero cost to outfit the place. What you and the other poster have said is, however, of concern. Have generalized maker spaces died off or turned into something unappealing?
I've had varying ideas about this over the years. I was a mentor for our local FRC (high school robotics) team for about five years. I enjoyed that very much. Yes, my kids were involved. I tried to re-enter that world and was faced with, well, stupid obstacles that very much telegraphed that, at least here, these teams have turned into unappealing political/ideological nightmares --rather than the "let's build cool robots!" feeling from the pre-pandemic era.
One thought was to create a maker space with specific focal activities. Three that come to mind are robotics, auto racing and RC flight. I wonder if that type of focus might mitigate the Etsy crowd effect you mentioned. I have nearly zero interest in having a bunch of people use my Haas CNC machines to mass produce crap for Etsy. One way to mitigate this might be to attach a cost to using the equipment for making anything to sell anywhere. For example, using a Haas VF-2 might cost $200 per hour plus consumables, etc. Not sure if that would work. You could also limit this sort of production-level work to a certain schedule and, maybe, it can only be done by or with staff. Not sure.
There are some successes. Maker Nexus in Silicon Valley pivoted to after-school activities for teens. Humanmade in San Francisco is mostly a job training center, and gets some government funding. There are some library-based maker spaces, but they're mostly basic 3D printing and crafts.
There's also pricing. Techshop started at $100/month and rose to $125 before they went bust. Humanmade is at $250. That's too high for casual users. If you raise the price too much, you mostly have customers who are there all the time, and now you don't have enough capacity. The financial numbers just didn't work out. Most of the remaining maker spaces have some degree of public financing, as part of a college or work training center.
Perhaps something like FedEx Office (formerly Kinkos). No membership. You go in and you pay to use equipment and resources. Of course, there would have to be levels of qualification someone would have to pass before being allowed to touch certain equipment. I suppose you could have classes (Solidworks, 3D printing, CNC machining, welding, etc.).
Writing that, at some level, it starts to feel complex. I say this in the context of my stated objective, which would be to stay busy at a low stress level after retirement. I am not sure that what I just described fits that model.
There's also a reality most don't want to think about. While, for the most part, dealing with the public is fun and interesting, there's always a very small percentage of people who behave badly. It's the old Tragedy of the Commons story. That's the part that none of us enjoy at all.
At TechShop, the big operational problems were tool deterioration and staff burnout. Tools tended to stabilize at the point where they're just above worn out. The drill bits and milling cutters were dull. The sandpaper on the belt sanders was worn almost smooth. The CNC mill needed a coolant change. The laser cutters had laser systems performing at about 50% of rated power, and you had to halve the feed rate. In a commercial shop, you'd fix things before they got that bad, because you're losing production. The same business logic does not apply to maker spaces.
The staff problem with TechShop was that they paid slightly above minimum wage, which is nowhere near enough to keep people with a broad range of shop skills. The big employee benefit was that you could take classes for free, so it was sort of an apprenticeship program. Over time, the staff tended to become the ones who couldn't get a job in a real shop.
Those are some of the operational problems you have to beat.
It's kind of funny to note that the negative comments here are ones calling it the Make (tm)(R) Magazine spaces and the positives are hackerspaces, as the real ones are.
