This is totally needless, although I had to build it. It's a type writer robot hand. Type on keys to action the fingers of the robot hand. With a glove on it you will surprise your friends and family... I am still waiting for my printer so it could be that some parts need adjustment. A derivative of MakerBot Filament Spool Holder by charlespax is used for the clips

Print all parts once. Fingers are all the same size only the thumb have different size.Check for pictures for to assemble. It isn't more difficult then Lego's. There is extra prints of keys and clips, in case printing doesn't work out good at first.Also you will need 5 rubber bands in order to get finger back in straight position,there is 2 hooks per finger for that. The hooks on the "base-hand" part need to be open with a knife at the small touching point. The "Keys-levier2" parts will need to be heated with hot gun in order to align with parts "Key-support". The "keys-support" part also need to be slightly shaped with hot gun so the keys don't hit each other. Glue gun is needed to put together "base-hand" and "base-hand-part".
