Interested in Star Wars and 3D printing? Well, then, this might just be the project for you. BB8BuildersClub user MontyBug has posted the build records of his 3D-printed model BB-8 droid from the new Star Wars: The Force Awakens film.
The project is made up of a number of different 3D-printed parts, and even has an Arduino board inside for things like the lights. Each piece is separately printed and then glued together. Unfortunately, the BB-8 doesn't roll around just yet, but MontyBug says that he's working on changing that.
The BB-8 Builders Club is a closed Facebook group that is, according to the page, dedicated to not building BB-8 (although judging by the name I would assume that they actually do want to build BB-8, they just don't want Lucasfilm to sue them ...). The project itself took around 900 hours to print the 100 parts.
