Now this is cool. Wired.com published this article about a company called emachineshop.com. The concept is really simple: you design parts using their free downloadable CAD software, upload the finished CAD drawing to them, they build it, FedEx ships it. Once you’ve designed it you can price it out using a variety of materials. There’s no need to hunt through all of Home Depot for a weird part, just design it yourself.
