Hi guys,
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!!!
Regards
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!!!

I think it is ball shaped so that it equally aero in all orientations, and there are no torques due to aero trying to move it adversely.
Great design. I'm glad you went with the Mobius. There is a significant shortage of Mobius gimbals and plenty of GoPro gimbals on the market (albeit, none that look quite like this.) One question, though... it seems the ball has a lot of wasted space. Have you considered more of an egg shape? It might improve the aerodynamics, take up less space, and take advantage of the Mobius flat form factor.
I love it, being a gimbal designer myself. The way you have it open up is really well thought out. I'm a little surprised you used the 2804 on the yaw, it is a bit underpowered if you have wind resistance. I'm also surprised you didn't use all hollow shafted motors, like the 2606 from Hobbyking. I imagine routing the flex wiring being challenging without it. Great design either way
looks really cool. make a GoPro version :)
very cool, good work. Would be nice to make a gopro version :)
This looks really great and has been on my to do list for a while now. If you upload your design to shapeways I believe that you can put a price on it so that folks can order the printed parts from shapeways, and you get some amount of money that you choose automatically.
