I couldn't resist to write such a title, sorry!
The sanding process of my R2 unit is a really long task, so I wished to find something else to make while not working on that project.
I thought to try to design a droid from the Star Wars universe, but it should have been something "new", something that no one had already tried to make by 3D printing. My choiche was a TT-8L doorkeeper from episode VI.
