Go to the fridge and take out an egg. Study it for as long as you like, but no measurements or drawings. Put the egg back! (honesty here is important).
Go to your workshop, choose any material you like (wood, plastic. alumininum, or whatever), go to your lathe or milling machine, and try to replicate that egg as accurately as possible (shape and size).
Take pictures of your creation next to an ordinary hens egg, and post your pictures here. No prizes, just pride in your workmanship.
Shape away!
