Robot arm

I made this robot arm design a few years back, based on simone giertz's soup robot.
Back than i did not have a 3d printer yet and made first made it out of foamboard and later out of wood.
Now that I have a 3d printer, this was the first thing I made and printed.
This is designed around 3 9gram servo's and i connect it up to a regular rc place reciever and controller.
I printed mine in sepperate parts, because my bed is warped and big surface area prints dont end very well.
I suggest using supports for the box part because it has some tiny overhang on the pin.
