Family business improve vastly by 3d printing

My wifes family runs chicken farms for a living. They made a clip that helps with the feeders via Fusion 360 and printed it on an Ender 3. Later on, her uncle patented the idea and took to the people that supply the chickens for the whole state they are based in. The person said that want the clips in all of the houses. We are talking about over 1 million of these pieces! Their family is going to be very happy soon from a hobby that turned profitable! I cannot say how proud and excited I am that this is happening for them. http://bit.ly/2GcUTc0
