If you have a few gallinaceous (hens, or chickens for friends), you may find yourself quickly having to manage a stock of eggs.That's where your 3D printer comes in handy.Print the supports, put them on a metal bar. (You can also print it but for less than 5$ atdo-it-yourself store the 2m bar in chromed metal, you really have to want to spoil your life...).You find a piece of wood, with a 28 mm hole, put the bar inside and you get a foot. You can also print it, but see the previous chapter, and it's very painful to collect 3 dozen eggs on the kitchen tile ...The metal bar is to be cut at 45cm, and is 25 mm in diameter.With a 4$99 bar, you can even make one for your mother-in-law... a cheap gift for Christmas.

The rooster is there to plug the hole in the bar, and to monitor the production of the pullets .
