let me introduce my latest project, a 3D printed gimbal for MobiusHD camera. I call it GimBALL regarding of it's shape...
My goal was to make a closed, aerodynamic shaped gimbal, which can be used in the front of a plane (ie. X-UAV Talon), up to 100 km/h airspeed. So I tried to make thisthing as aerodynamic as it can be. For drive I choosed three size of motors, according to the weight they have to rotate.
The smallest is for pitch axis, a HK 2206-140KV, RCTimer 2212 is on roll and RCTimer 2804 hollow shaft is on yaw axis. I'll use a basecam 8bit 3-axis controller placed inside my plane's fuselage.
For easy operation and FPV purposes, I made a small PCB from an USB plug which will be fixed inside the GimBALL. So Mobius have to be plugged in, that's all. There is a hole for easy SD-card removing and also there are holes for buttons and LED.
I checked the main parts with FEM analysis to be sure they are optimized for external loads (parts weight and wind force):
All parts will be printed using a Stratasys 3D-printer (using FDM technology). Total weight including MobiusHD and motors, screws will be around 280 g (+-15g).
Here are some renders about details:
Next step will be the parts producing and assembly (PART2) and final testing (PART3). So stay tuned!!!

Adrian
PS.: I'm not planning to produce this GimBALL but if anybody interrested in start producing, just write me an email (nhadrian@gmail.com), since I'm willing to sell 3D models - basically trade for smaller parts that are useful for my projects!!! But I don't have any time to produce parts and take support for customers, etc ... so please don't ask me how much will be a ready- to -use GimBALL...Thank you for your understanding!!!

Why don't you produce this ? It would sell like hell
love it! looks like the looks of the Oblivion 's drones (the movie).
those who asked for a gopro version ...
have a look at kahoneys design on shapeways:

Looks awesome. I think it's probably too complicated for my 3d printer, but I would love something similar.
shut up and take my money............I love it and want one
Very nice work! What program did you use to design this in?
Looks awsome, I would recoment the brushless motors with hollow shaft as well, and considder making some "push" rods from the top and down to the buttons on the Mobiu, instead of jsut having holes
Parts are ready (I'll post PART2 soon), not an issue for a Stratasys, all parts are really nice finished. (But you are right, might be difficult for a low cost printer, especially if doesn't use support material like Stratasys does.)
Nice design, a bit complex for a low cost FDM 3D printer, It seems to be made for a much more expensive SLS/SLA 3D Printer.
That's right. If you use an egg-shape and point gimbal to the ground, it will have torque due to wind.
Regarding Yaw motor, I hope it will have enough power, I'd like to use it in follow-mode, just to shoften plane's yaw oscillation.
