3d printed robotic arm

well , i am not going to discuss a lot about bed temps and so on ! i want to think that no newbie to 3d printing will try to print this ! the only note that i want to make is that the gears need to be printed with high resolution in order to mesh ! they are really snug fit , but they work ! you can see how to build it in this video ! https://www.youtube.com/watch?v=g2QkaCshTuE
