brushles 3d gimbal arms

This is a 3 pieces frame for a gimbal with brushless motors i purchased the motors from aliexpress as well as the controller board using an old alexmos 8bit controller on mine, or any other alexmos could work, it would all depend on your camera weight and current specs of the gimbal controller that you would choose i was using a SL1 which is very light and it uses half of the max power without heating up, which would be the main enemy of this plastic build, i used carbon fiber fillament with excelent results, very little springyness, it works just fine, could be stronger with a different material maybe or a heat resistant plastic if you would want to get more power on small motors, currently using about 4.5cm diameter brushless motors suggestions are to use a 32 bit controller with 2 imus because the 8 bit 1 imu that im using usually gets errors for being confused on which motor it should control after turning 20 degrees on any axis, regardless of that i think it does a better job that me trying to hold it still is lighter than must diy kits using only motor nuts for fastening saving over half nuts on weight usually needed on those kits, this makes more time if flown with a drone or easier to hand carry 3 parts that on a 1mm nozzle would be done in 3 hours thats 1 hour each piece thats thanks to its flat sides wich can be seated on the build plate, you should put support everywhere but i managed to get descent prints on no support prints. I used only carbon fiber filament and parts seem to work fine, maybe more structure to the roll to pitch arm would help with a little flexing it is having, but using lighter motors and camera could eliminate the need for tweaks. Design is very easy in this and could be tweaked from any ortographic view to match special dimensions or weright distributions
