This is turning out great, buddy!

Haven't You considered making a mass production of such "balls" You've vacume formed for the droid-brain housing?

Just couldn't help thinking, how many cool stuff can be also made from them: Luke's remote, droid-interrogator from the Death Star, Hoth ion canon and lots of more - spheres are a valuable thing for sci-fy modeling, and geographical globes are not always fitting the requirements of the project.
