Do maker spaces federate in any way? Examples I can think of are a bit bougie, but golf clubs or professional clubs where there are sister chapters/courses in other regions.
It would be so cool to visit a maker space when in a different town (or country) with some degree of attached reputation (won't damage things, know the safety rules, history of good conduct).
Sort of. We work pretty closely with the nearest makerspace and have a thing where we will split membership fees of people who wish to join both (a common thing if you live half way between the two places).
Unfortunately, there is nothing like this at the national or global level that I am aware of.
