A vRoomba - Pull Back Motor Vacuum Robot

I measured a simple "Pull Back" style motor that I found in a dollar-store toy, and recreated the "Cat on a Vacuum" meme that you see on YouTube videos with this toy.

The design of the robotic sweeper was entirely by eyeball, and made just thick enough to hide the motor. No specific brand of automatic carpet cleaning device is expressed or implied, of course. Any resemblance to an actual trademarked product is just as coincidental as a company naming itself with a lowercase-i-capital-noun format (like Apple products) or naming itself after famous science fiction stories (like Asimov's books).

For some reason, Slic3r 0.9.9 complains about it being non-manifold, but Blender cannot find any fault with the STL. The slicing results are perfect. I recommend the concentric top fill to complement the contours of the robot.
