We hadn't either until just recently. We had a customer come in a few months ago from a local (Milwaukee) chapter and we discussed it at length. They're cropping up all across the country and it's one of the coolest concepts we've heard about in a long time.
Everyone has a project that they're working on but might not have the resources to complete it. It might be steel fabricating, 3D printing, fabric work, etc., a makerspace is a place you can go to and complete your project or just play around and create your dream. They have equipment available for you to use and again, it runs the gamut from metal working to artwork.
Here's a link to the Milwaukee site: http://milwaukeemakerspace.org/. If you have a project you're working on but don't have the necessary equipment to complete it you need to contact these people. If you're not in the local area just do a makerspace search, you'll probably find one near you.
If you're a makerspace owner or a makerspace member, local or otherwise, we encourage you to get in touch with us. We support what you're doing and would love to hear from you!
