This is my version of a xiaomi yi case for the realacc x210. It is need to be printed in flexible filament, tpu for example. To install it is enough with a zip tie and the frame screws.
Also is needed to remove the original action cam support which come with the frame. Here you have a fpv camera holder for that frame:
To print it is neccesary to use supports, and I use a 20% of infill with 0.8 mm of wall.
