Description
This is a GoPro Gimbal I've designed around the GBM2804 Hollow Shaft Motors for the White Sheep.
It allows for nice cable management with cable guides and by routing them through the axis they can move freely without tension from the angle of the gimbal.
Some parts were salvaged from a cheap Ebay Gimbal like the Vibration dampeners and the Alexmos Board. (I have some arms for these kind of motors aswell ... these files are marked as MADPOWER)
The GoPro ist mounted in a Housing and secured by a velcro strap.
Here comes the tricky part ... You have to sew :) (It's really not that difficult with a sewing machine ... Or just ask your mom)
(If you like to live dangerously you could also just trust the friction of the housing to hold it)
The housing allows for a slim FPV cable to the GoPro which you can get here :

What to Print?
One of everything - except:
2x TopCap.STL (if you use no FPV Camera)
1x TopCap.STL 1x FPVMount.STL (for FPV Board Cam)
ARMGBM2804Fix has no adjustment to balance the Gimbal, but is pretty much the balance point for it. Aswell you can mount the Zip Tie inside the arm, so its flush.
Maybe I will incorporate that into the normal Arm ...
