I have recreated an improved version of the Original created by GEPRC for the o3 unit. This version is more aerodynamic, has a much larger and more precise airflow inlet, along with a small lower air passage that improves the cooling of the bottom of the o3 and other elements that may be placed on the mount. Apart from this I have managed to reduce the weight of 2 g less than the original. It is possible to further reduce the weight of this element, but we would lose rigidity. That is why it has a balance between strength and weight.
I recommend using Transparent TPU, as the final result is much nicer.
Thanks to @Treverse_2258907 for the hole position base.
If you use it write me comments and photos to see your drones. So I can improve in future designs
