BB8 Robot project

If you did not know already BB8 is a Star Wars Droid from Episode 7 The Force Awakens. For my project I have decided to build a fully functional BB8 droid. So far I have the main body constructed, as well as the head with the details in pencil applied. I have also 3d printed his eyelid and holo projector. To build my droid I am following an Intractable.
