Here's my rendition of Gonk, my favorite droid. I made him to be in scale with my collection of 1/12 Bandai Star Wars models.
This is my first attempt at designing for 3d print, so there are a couple issues I hope to work out for future versions.
He has to print with a lot of support. I recommend printing him on his head so you get a nice flat surface there. The support between his legs was the trickiest to remove.
The join of the power cables to his legs and feet is very delicate and broke off on both of my prototypes.
