A man had a part break on his Bugaboo, a really nice and pricey stroller. The official repair center said it would cost $250 to replace the part. So the man said, forget that, and used a 3D printing service, which creates three-dimensional objects by laying down successive layers of material, to get it fabricated in stainless steel for $25 instead. Schweet!
He also made an Instructable to show others how he did it. I wonder what other seemingly expensive parts could be made on the cheap using a 3D printer?
