Since I discovered it, I've been eagerly awaiting the ship date of the Ascent Aerosystems Sprite drone. It's a coaxial, ruggedized, waterproof drone meant for backpackers. In fact, in early development it appears it was called the "backpacker drone".
It's a pretty unique little drone, and I'm looking forward to it shipping. In the mean time, Ascent Aerosystems has made a small mockup of the Sprite available for download on thingiverse. I had most of the right colors on hand, so I decided to take a crack at it!
All in all, I'm pretty happy with my printed model. It comes out to about 7.5" tall, and the rotors can actually be moved. I wish I had printed the blades on their leading edge, however. Printing them with the bottom side down led to quite a bit of nasty scarring and debris from support material removal.
