It had to be done! Following the awesome work by Skimbal on his lego dudes, and the Vader head by lampmaker... I Present...
A Giant Darth Vader.
I modified the body slighly to add some Vader details ... and the head to fit the standard circular plug.
Print the pieces , and press together.
Oh, and you'll want to make a cloak out of black material too .... or print it from on of the cool designs by others.
There are now 2 versions of the head - a single piece or Helmet style to fit over a standard head.
...and then print a lightsaber for him
The Handle has some extra material at the rod end to allow easier printing (Vertical) , so this needs to be trimmed off to achieve the right look.
