I can see drones hitting that... I can envision lots of drones in the sky, and some falling down and hurting someone, but 3d printing? Who could ever be pissed off about that? 3d printing is very akin to a molding-clay hobby, I just can't conceive of any harm done through 3d printing. (Hobby CNC milling is getting big these days... now that I can imagine being dangerous/too noisy, but even those complaints are small)
