To a degree this is true, but a perfect example I just ran into today is this: I&#x27;ve got 3 sonar range finders to mount on my robot chassis which has been made from aluminum- I could painstakingly hand craft three holders out of wood or metal, spending at least an hour or two per holder, or I can find a model on the Internet, modify it to fit my application and print all three at once in under 90 minutes. You shouldn&#x27;t be 3D printing everything, but it is INCREDIBLY useful for small part fabrication.
