Check this new series of videos by genius maker James Bruton. He is well known youtuber among the makers community. He makes amazing models based on pop-culture characters, and his videos are great source of knowledge about arduino, electronics and 3d printing. He previously showed us how he built 3 versions of full scale BB8 and now did new droid from Star Wars The Last Jedi.
If you enjoyed, I higly recommend signing to his channel XRobots. He always comes with fantastic ideas and solutions. Very inspirational.
