3689626935?profile=originalHi 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!!!



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

  • Yes! I'd be interested in a gopro version that accommodated a 32bit alexmos system
  • 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.
