Primbal V3 - 3 Axis Brushless Gimbal for Yi/GoPro

thingiverse

Primbal V3 is here. It has been over a year since I released the original Primbal, one of the only 3D printable brushless gimbal designs. Since then, I have been experimenting and revising the design to make Primbal even better. Primbal V3 implements stronger, stiffer arms that make the gimbal more resistant to vibrations. The camera mount is also more rigid, with a system to hold the camera from both the back and front. Additionally, there are now four different isolator options available to suit your needs. The result is a more robust, versatile gimbal to bring you silky smooth video. This gimbal is composed of 14 printed parts that are all printer-friendly. All STLs are in the proper printing position, requiring no reorienting. All three axes (pitch, roll, yaw) are fully adjustable to perfectly balance the gimbal. This gimbal is designed to best perform with a Xiaomi Yi, but it can be modified to fit GoPros and other similar action cams. **Specs:** **Parts:** 14 Printed **Hardware:** 2 x M1.6 Bolt and Nut 12mm (M2 works as well) 8 x M2 Bolt 8mm 2 x M2 Nut 4 x M3 Bolt 4mm 2 x M3 Bolt 6mm **Motors:** 2804 size for yaw (35mm diameter) 2206/2804 size for roll 2206 size for pitch (28mm diameter) Confirmed to Fit: [Hobbyking 2804-210Kv](https://hobbyking.com/en_us/2804-210kv-brushless-gimbal-motor-ideal-for-gopro-to-compact-style-cameras.html?___store=en_us) [Hobbyking 2206-140Kv](https://hobbyking.com/en_us/2206-140kv-brushless-gimbal-motor-ideal-for-gopro-style-cameras.html?___store=en_us) [Rctimer GBM2804](http://rctimer.com/product-1075.html) Might Fit: [Quanum 2208](https://hobbyking.com/en_us/quanum-2208-precision-brushless-gimbal-motor-gopro-size-100-200g.html?___store=en_us) [DYS BGM2208](https://www.banggood.com/DYS-BGM2208-70T-Brushless-Gimbal-Motor-For-Gopro3-3-FPV-Camera-Mount-p-949265.html) **Controller:** Any 3-axis brushless gimbal controller to externally control the gimbal. I recommend a Storm32 board. **Weight:** Approximately 250g with camera, 175g without **Range of Motion** Pitch: -90 +90 Roll: -45 +45 Yaw: Depends on wiring **Balancing:** To balance the roll and yaw axes, loosen the bolts holding the arms to the roll/yaw motors and slide the bolt spacer along the adjustment slot. For the pitch axis, a similar process is done with the pitch adjuster to adjust up and down. To adjust the pitch axis back, add spacers between the bolts holding the camera frame to the pitch adjuster. The Xiaomi Yi should balance perfectly on the pitch axis without any adjustments to forward/back. **Different Motors/Parts:** GoPro Hero 3/4 models can fit the gimbal with minor modification. Newer GoPro models may require more care. If you need the design modified to fit a different gimbal motor or part, let me know! I can modify the design for your needs. However, there are no guarantees as there is only so much that can be done without the physical parts in hand.
