Chris Milnes had never 3D printed anything when he invented an iPhone accessory he desperately needed. While the Square credit card reader makes his life easier as a business owner, it tends to spin and twist during use. His simple design, the Square Helper, connects the Square unit to an iPhone or iPad and prevents it from twisting, saving the merchant time and hassle. With his MakerBot Replicator 2 Desktop 3D Printer, Chris has a factory on his desk for making high-resolution, durable units. Even better, the Square Helper accessory is selling for a big profit, without any need for injection molding. Chris’s story is a great example of how a MakerBot can empower anyone with an idea to become an inventor, a manufacturer, and an entrepreneur.
