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!!!

  • Hi, looks great.

    No, I use the other part of the arm (the right one on your photo) just to hide the cables. coming out (i2c, video signal, 5V for mobius).

    Good luck!!!

  • 3701993823?profile=originalI got your Gimball 3d printed at my local library, very nice design. Is there supposed to be a hinge on the opposite side of the pitch gimbal or do we just make our own?

  • Adrián:

    Your design and renderings are truly exceptional and I complement you on your capabilities.  I believe that you could easily license or sell your design to a company that I was discussing a similar situation with today (a different product) and I would be honored to handle the introduction for you - or even represent your interests in obtaining fair compensation for your creativity and execution.  You would do much better than trading for the odd parts here and there - you would have your pick of the catalog!

  • Oh I see it, Wow- looks awesome!

  • Id like to see it printed!!

  • A Mobius gimbal like this inside the nose of an RVjet would be really nice.

  • For printed gimbal the temperature is critical parameter

  • Daniel, I not test  GB36 it is heavy for me and without hollow shaft. If rewind 2804 it will be better. But my choice is iPower GBM2208H low weight, more power then 2804, hollow shuft, stay warm after hours indoor operation at 160 power value.


  • Evgeniy, I agree the 2804 isn't strong. However with the Alexmos controller I was able to get it to work fairly well with a 3-axis GoPro setup. The settings were high (like 150 power out of 250), which made it hot and very torquey. There aren't make hollow shafted motors that are under 100g. You're best bet is the Tiger GB36-1.
